As evidenced by the leak fixes in the previous commit, the "const" in
git_config_get_string_const() clearly misleads people into thinking that
it does not allocate a copy of the string. We can fix this by renaming
it, but it's easier still to just drop it. Of the four remaining
callers:
- The one in git_config_parse_expiry() still needs to allocate, since
that's what its callers expect. We can just use the non-const
version and cast our pointer. Slightly ugly, but the damage is
contained in one spot.
- The two in apply are writing to global "const char *" variables, and
need to continue allocating. We often mark these as const because we
assign default string literals to them. But in this case we don't do
that, so we can just declare them as real "char *" pointers and use
the non-const version.
- The call in checkout doesn't actually need a copy; it can just use
the non-allocating "tmp" version of the function.
The function is also mentioned in the MyFirstContribution document. We
can swap that call out for the non-allocating "tmp" variant, which fits
well in the example given.
We'll drop the "configset" and "repo" variants, as well (which are
unused).
Note that this frees up the "const" name, so we could rename the "tmp"
variant back to that. But let's give some time for topics in flight to
adapt to the new code before doing so (if we do it too soon, the
function semantics will change but the compiler won't alert us).

There are two functions to get a single config string:
- git_config_get_string()
- git_config_get_string_const()
One might naively think that the first one allocates a new string and
the second one just points us to the internal configset storage. But
in fact they both allocate a new copy; the second one exists only to
avoid having to cast when using it with a const global which we never
intend to free.
The documentation for the function explains that clearly, but it seems
I'm not alone in being surprised by this. Of 17 calls to the function,
13 of them leak the resulting value.
We could obviously fix these by adding the appropriate free(). But it
would be simpler still if we actually had a non-allocating way to get
the string. There's git_config_get_value() but that doesn't quite do
what we want. If the config key is present but is a boolean with no
value (e.g., "[foo]bar" in the file), then we'll get NULL (whereas the
string versions will print an error and die).
So let's introduce a new variant, git_config_get_string_tmp(), that
behaves as these callers expect. We need a new name because we have new
semantics but the same function signature (so even if we converted the
four remaining callers, topics in flight might be surprised). The "tmp"
is because this value should only be held onto for a short time. In
practice it's rare for us to clear and refresh the configset,
invalidating the pointer, but hopefully the "tmp" makes callers think
about the lifetime. In each of the converted cases here the value only
needs to last within the local function or its immediate caller.

As with the recent change to parse_config_key(), the best type to return
a string length is a size_t, as it won't cause integer truncation for a
gigantic key. And as with that change, this is mostly a clarity /
hygiene issue for now, as our config parser would choke on such a large
key anyway.
There are a few ripple effects within the config code, as callers switch
to using size_t. I also adjusted a few related variables that iterate
over strings. The most unexpected change is that a call to strbuf_addf()
had to switch to strbuf_add(). We can't use a size_t with "%.*s",
because printf precisions must have type "int" (we could cast, of
course, but that would miss the point of using size_t in the first
place).

We return the length to a subset of a string using an "int *"
out-parameter. This is fine most of the time, as we'd expect config keys
to be relatively short, but it could behave oddly if we had a gigantic
config key. A more appropriate type is size_t.
Let's switch over, which lets our callers use size_t as appropriate
(they are bound by our type because they must pass the out-parameter as
a pointer). This is mostly just a cleanup to make it clear this code
handles long strings correctly. In practice, our config parser already
chokes on long key names (because of a similar int/size_t mixup!).
When doing an int/size_t conversion, we have to be careful that nobody
was trying to assign a negative value to the variable. I manually
confirmed that for each case here. They tend to just feed the result to
xmemdupz() or similar; in a few cases I adjusted the parameter types for
helper functions to make sure the size_t is preserved.

Previously when iterating through git config variables, worktree config
and local config were both considered "CONFIG_SCOPE_REPO". This was
never a problem before as no one had needed to differentiate between the
two cases, but future functionality may care whether or not the config
options come from a worktree or from the repository's actual local
config file. For example, the planned feature to add a '--show-scope'
to config to allow a user to see which scope listed config options come
from would confuse users if it just printed 'repo' rather than 'local'
or 'worktree' as the documentation would lead them to expect. As well
as the additional benefit of making the implementation look more like
how the documentation describes the interface.
To accomplish this we split out what was previously considered repo
scope to be local and worktree.
The clients of 'current_config_scope()' who cared about
CONFIG_SCOPE_REPO are also modified to similarly care about
CONFIG_SCOPE_WORKTREE and CONFIG_SCOPE_LOCAL to preserve previous behavior.

$ git ls-files \*.{c,h} |

Files under `compat/` are intentionally excluded as some are directly
copied from external sources and we should avoid churning them as much

Then, leftover instances of extern were found by running

Note that the regex used specifically excludes function variables which
_should_ be left as extern.

If a user explicitly sets
[index]
threads = true
to read the index using multiple threads, ensure that index writes
include the offset table by default to make that possible. This
ensures that the user's intent of turning on threading is respected.
In other words, permit the following configurations:
- index.threads and index.recordOffsetTable unspecified: do not write
the offset table yet (to avoid alarming the user with "ignoring IEOT
extension" messages when an older version of Git accesses the
repository) but do make use of multiple threads to read the index if
the supporting offset table is present.
This can also be requested explicitly by setting index.threads=true,
0, or >1 and index.recordOffsetTable=false.
- index.threads=false or 1: do not write the offset table, and do not
make use of the offset table.
One can set index.recordOffsetTable=false as well, to be more
explicit.
- index.threads=true, 0, or >1 and index.recordOffsetTable unspecified:
write the offset table and make use of threads at read time.
This can also be requested by setting index.threads=true, 0, >1, or
unspecified and index.recordOffsetTable=true.
Fortunately the complication is temporary: once most Git installations
have upgraded to a version with support for the IEOT and EOIE
extensions, we can flip the defaults for index.recordEndOfIndexEntries
and index.recordOffsetTable to true and eliminate the settings.

In addition, if the untracked cache is turned on valid_cached_dir() can

correctly without using the return value, though.
In the future, we may find other variables that only allow an
integer that specifies "this many days" or other unit of time, and
when it happens we may need to drop "_days" suffix from the name of
the function and instead pass the "scale" value as another parameter.

Teach the config machinery to read config information from a repository
object. This involves storing a 'struct config_set' inside the
repository object and adding a number of functions (repo_config*) to be
able to query a repository's config.
The current config API enables lazy-loading of the config. This means
that when 'git_config_get_int()' is called, if the_config_set hasn't
been populated yet, then it will be populated and properly initialized by
reading the necessary config files (system wide .gitconfig, user's home
.gitconfig, and the repository's config). To maintain this paradigm,
the new API to read from a repository object's config will also perform
this lazy-initialization.
Since both APIs (git_config_get* and repo_config_get*) have the same
semantics we can migrate the default config to be stored within
'the_repository' and just have the 'git_config_get*' family of functions
redirect to the 'repo_config_get*' functions.

Historically we could assume that the per-repository config lives at
'gitdir/config', but since worktrees were introduced this isn't the case
anymore. There is currently no way to specify per-worktree
configuration, and as such the repository config is shared with all
worktrees and is located at 'commondir/config'.
Many users of the config machinery correctly set
'config_options.git_dir' with the repository's commondir, allowing the
config to be properly loaded when operating in a worktree. But other's,
like 'read_early_config()', set 'config_options.git_dir' with the
repository's gitdir which can be incorrect when using worktrees.
To fix this issue, and to make things less ambiguous, lets add a
'commondir' field to the 'config_options' struct and have all callers
properly set both the 'git_dir' and 'commondir' fields so that the
config machinery is able to properly find the repository's config.

Since there is no implementation of the function 'git_config_iter',
let's stop exporting it and remove the prototype from config.h.
