If we are trying to resolve deltas for a long delta chain composed
of multi-megabyte objects we can easily run into requiring 500M+
of memory to hold each object in the chain on the call stack while
we recurse into the dependent objects and resolve them.
We now use a simple delta cache that discards objects near the
bottom of the call stack first, as they are the most least recently
used objects in this current delta chain. If we recurse out of a
chain we may find the base object is no longer available, as it was
free'd to keep memory under the deltaBaseCacheLimit. In such cases
we must unpack the base object again, which will require recursing
back to the root of the top of the delta chain as we released that
root first.
The astute reader will probably realize that we can still exceed
the delta base cache limit, but this happens only if the most
recent base plus the delta plus the inflated dependent sum up to
more than the base cache limit. Due to the way patch_delta is
currently implemented we cannot operate in less memory anyway.

If we free the data stored within a base_data we need the struct
object_entry to get the data back again for use with another dependent
delta. Storing the object_entry* in base_data makes it simple to call
get_data_from_pack() to recover the compressed information.
This however means that we must add the missing base object to the end of
our packfile prior to calling resolve_delta() on each of the dependent
deltas. Adding the base first ensures we can read the base back from the
pack we are indexing, as if it had been included by the remote side.

We need to release earlier inflated base objects when memory gets
low, which means we need to be able to walk up or down the stack
to locate the objects we want to release, and free their data.
The new link/unlink routines allow inserting and removing the struct
base_data during recursion inside resolve_delta, and the global
base_cache gives us the head of the chain (bottom of the stack)
so we can traverse it.

We need to discard base objects which are not recently used if our

To support tracking the available base objects we combine the
pointer and size into a struct. Future changes would allow the
data pointer to be free'd and marked NULL if memory gets low.

When adding a new submodule in place, meaning the user created the
submodule as a git repo in the superproject's tree first, we don't go
through "git submodule init" to register the module. Thus, the
submodule's origin repository URL is not stored in .git/config, and no
subsequent submodule operation will ever do so. In this case, assume the
URL the user supplies to "submodule add" is the one that should be
registered, and do so.

This change makes "submodule add" much more strict in the arguments it
takes, and is intended to address confusion as recently noted on the
git-list. With this change, the required syntax is:
$ git submodule add URL path
Specifically, this eliminates the form
$ git submodule add URL
which was confused by more than one person as
$ git submodule add path
With this patch, the URL locating the submodule's origin repository can be
either an absolute URL, or (if it begins with ./ or ../) can express the
submodule's repository location relative to the superproject's origin.
This patch also eliminates a third form of URL, which was relative to the
superproject's top-level directory (not its repository). Any URL that was
neither absolute nor matched ./*|../* was assumed to point to a
subdirectory of the superproject as the location of the submodule's origin
repository. This URL form was confusing and does not seem to correspond
to an important use-case. Specifically, no-one has identified the need to
clone from a repository already in the superproject's tree, but if this is
needed it is easily done using an absolute URL: $(pwd)/relative-path. So,
no functionality is lost with this patch. (t6008-rev-list-submodule.sh did
rely upon this relative URL, fixed by using $(pwd).)
Following this change, there are exactly four variants of
submodule-add, as both arguments have two flavors:
URL can be absolute, or can begin with ./|../ and thus names the
submodule's origin relative to the superproject's origin.
Note: With this patch, "submodule add" discerns an absolute URL as
matching /*|*:*: e.g., URL begins with /, or it contains a :. This works
for all valid URLs, an absolute path in POSIX, as well as an absolute path
on Windows).
path can either already exist as a valid git repo, or will be cloned from
the given URL. The first form here eases creation of a new submodule in
an existing superproject as the submodule can be added and tested in-tree
before pushing to the public repository. However, the more usual form is
the second, where the repo is cloned from the given URL.
This specifically addresses the issue of
$ git submodule add a/b/c
attempting to clone from a repository at "a/b/c" to create a new module
in "c". This also simplifies description of "relative URL" as there is now
exactly *one* form: a URL relative to the parent's origin repo.

Linus reported that the bash completion for git show often dropped
the ref portion of the argument (stuff before the :) when trying
to complete a file name of a file in another branch or tag.
Björn Steinbrink tracked it down to the gvfs completion script
which comes standard on many Fedora Core based systems. That is
removing : from COMP_WORDBREAKS, making readline treat the entire
argument (including the ref) as the name that must be completed.
When the git completion routines supplied a completion of just the
filename, readline replaced everything.
Since Git users often need to use "ref:path" or "ref:ref" sort of
arguments, and expect completion support on both sides of the :
we really want the : in COMP_WORDBREAKS to provide a good user
experience. This is also the default that ships with bash as it
can be useful in other contexts, such as rcp/scp.
We now try to add : back to COMP_WORDBREAKS if it has been removed
by a script that loaded before us. However if this doesn't work
(as the : is stripped after we load) we fallback in the completion
routines to include "ref:" as part of the prefix for completions,
allowing readine to fully insert the argument the user wanted.

The system's default browser for displaying HTML help pages is now used
directly on Windows, instead of launching git-web--browser, which
requires a Unix shell. Avoiding MSYS' bash when possible is good
because it avoids potential path translation issues. In this case it is
not too hard to avoid launching a shell, so let's avoid it.
The Windows-specific code is implemented in compat/mingw.c to avoid
platform-specific code in the main code base. On Windows, open_html is
provided as a define. If open_html is not defined, git-web--browse is
used. This approach avoids platform-specific ifdefs by using
per-function ifdefs. The "ifndef open_html" together with the
introductory comment should sufficiently warn developers, so that they
hopefully will not break this mechanism.

Expanding system paths relative to git_exec_path can be used for

This commit moves common code to a new function system_path(). System
paths that are to be interpreted relative to git_exec_path are passed to
system_path() and the return value is used instead of the original path.
system_path() prefixes a relative path with git_exec_path and leaves
absolute paths unmodified. For example, we now write
template_dir = system_path(DEFAULT_GIT_TEMPLATE_DIR);
