5f03e5126d refs: cleanup directories when deleting packed ref
When deleting a packed ref via 'update-ref -d', a lockfile is made in
the directory that would contain the loose copy of that ref, creating
any directories in the ref's path that do not exist. When the
transaction completes, the lockfile is deleted, but any empty parent
directories made when creating the lockfile are left in place.  These
empty directories are not removed by 'pack-refs' or other housekeeping
tasks and will accumulate over time.

When deleting a loose ref, we remove all empty parent directories at the
end of the transaction.

This commit applies the parent directory cleanup logic used when
deleting loose refs to packed refs as well.

133a4fda59 mailinfo: allow stripping quoted CR without warning
In previous changes, we've turned on warning for quoted CR in base64 or
quoted-printable email messages. Some projects see those quoted CR a lot,
they know that it happens most of the time, and they find it's desirable
to always strip those CR.

Those projects in question usually fall back to use other tools to handle
patches when receive such patches.

Let's help those projects handle those patches by stripping those
excessive CR.

0b689562ca mailinfo: warn if CRLF found in decoded base64/QP email
When SMTP servers receive 8-bit email messages, possibly with only
LF as line ending, some of them decide to change said LF to CRLF.

Some mailing list softwares, when receive 8-bit email messages,
decide to encode those messages in base64 or quoted-printable.

If an email is transfered through above mail servers, then distributed
by such mailing list softwares, the recipients will receive an email
contains a patch mungled with CRLF encoded inside another encoding.

Thus, such CR (in CRLF) couldn't be dropped by "mailsplit".
Hence, the mailed patch couldn't be applied cleanly.
Such accidents have been observed in the wild [1].

Instead of silently rejecting those messages, let's give our users
some warnings if such CR (as part of CRLF) is found.

3a7f0908b6 clean: remove unnecessary variable
The variable `matches` used to hold the return of a `dir_path_match()`
call that was removed in 95c11ecc73 ("Fix error-prone fill_directory()
API; make it only return matches", 2020-04-01). Now `matches` will
always hold 0, which is the value it's initialized with; and the
condition `matches != MATCHED_EXACTLY` will always evaluate to true. So
let's remove this unnecessary variable.

Interestingly, it seems that `matches != MATCHED_EXACTLY` was already
unnecessary before 95c11ecc73. That's because `remove_directories` is
always set to 1 when we have pathspecs; So, in the condition
`!remove_directories && matches != MATCHED_EXACTLY`, we would either:

- have pathspecs (or have been given `-d`) and ignore `matches` because
  `remove_directories` is 1; or

- not have pathspecs (nor `-d`) and end up just checking that
  `0 != MATCHED_EXACTLY`, as `matches` would never get reassigned
  after its zero initialization (because there is no pathspec to match).

d582992e80 mailinfo: load default metainfo_charset lazily
In a later change, we will use parse_option to parse mailinfo's options.
In mailinfo, both "-u", "-n", and "--encoding" try to set the same
field, with "-u" reset that field to some default value from
configuration variable "i18n.commitEncoding".

Let's delay the setting of that field until we finish processing all
options. By doing that, "i18n.commitEncoding" can be parsed on demand.
More importantly, it cleans the way for using parse_option.

This change introduces some inconsistent brackets "{}" in "if/else if"
construct, however, we will rewrite them in the next few changes.

This speeds up the compilation time of commands that use this library

That bug didn't matter in practice since the first line had all the

d4e2d15a8b streaming.c: move {open,close,read} from vtable to "struct git_istream"
Move the definition of the structure around the open/close/read
functions introduced in 46bf043807 (streaming: a new API to read from
the object store, 2011-05-11) to instead populate "close" and "read"
members in the "struct git_istream".

This gets us rid of an extra pointer deference, and I think makes more
sense. The "close" and "read" functions are the primary interface to
the stream itself.

Let's also populate a "open" callback in the same struct. That's now
used by open_istream() after istream_source() decides what "open"
function should be used. This isn't needed to get rid of the
"stream_vtbl" variables, but makes sense for consistency.

de94c0eace streaming.c: stop passing around "object_info *" to open()
Change the streaming interface to stop passing around the "struct
object_info" the open() functions.

As seen in 7ef2d9a260 (streaming: read non-delta incrementally from a
pack, 2011-05-13) which introduced the "st->u.in_pack" assignments
being changed here only the open_istream_pack_non_delta() path need
these.

So let's instead do this when preparing the selected callback in the
istream_source() function. This might also allow the compiler to
reduce the lifetime of the "oi" variable, as we've moved it from
"git_istream()" to "istream_source()".

bc062ad001 streaming.c: remove {open,close,read}_method_decl() macros
Remove the {open,close,read}_method_decl() macros added in
46bf043807 (streaming: a new API to read from the object store,
2011-05-11) in favor of inlining the definition of the arguments of
these functions.

Since we'll end up using them via the "{open,close,read}_istream_fn"
types we don't gain anything in the way of compiler checking by using
these macros, and as of preceding commits we no longer need to declare
these argument lists twice. So declaring them at a distance just
serves to make the code less readable.

0d9af06e36 streaming.c: remove enum/function/vtbl indirection
Remove the indirection of discovering a function pointer to use via an
enum and virtual table. This refactors code added in
46bf043807 (streaming: a new API to read from the object store,
2011-05-11).

We can instead simply return an "open_istream_fn" for use from the
"istream_source()" selector function directly. This allows us to get
rid of the "incore", "loose" and "pack_non_delta" enum
variables. We'll return the functions instead.

The "stream_error" variable in that enum can likewise go in favor of
returning NULL, which is what the open_istream() was doing when it got
that value anyway.

We can thus remove the entire enum, and the "open_istream_tbl" virtual
table that (indirectly) referenced it.
