compat: fall back on __va_copy if available

Since an obvious implementation of va_list is to make it a pointer
into the stack frame, implementing va_copy as "dst = src" will work on
many systems.  Platforms that use something different (e.g., a size-1
array of structs, to be assigned with *(dst) = *(src)) will need some
other compatibility macro, though.

Luckily, as the glibc manual hints, such systems tend to provide the
__va_copy macro (introduced in GCC in March, 1997).  By using that if
it is available, we can cover our bases pretty well.

Discovered by building with CC="gcc -std=c89" on an amd64 machine:

Junio C Hamano [Fri, 4 Mar 2011 20:25:34 +0000 (12:25 -0800)]
apply: do not patch lines that were already patched

When looking for a place to apply a hunk, we used to check lines that
match the preimage of it, starting from the line that the patch wants to
apply the hunk at, looking forward and backward with increasing offsets
until we find a match.

Colin Guthrie found an interesting case where this misapplied a patch that
wanted to touch a preimage that consists of

                        }
                }

                return 0;
        }

which is a rather unfortunately common pattern.

The target version of the file originally had only one such location, but
the hunk immediately before that created another instance of such block of
lines, and find_pos() happily reported that the preimage of the hunk
matched what it wanted to modify.

Oops.

By marking the lines application of earlier hunks touched and preventing
match_fragment() from considering them as a match with preimage of other
hunks, we can reduce such an accident.

I also considered to teach apply_one_fragment() to take the offset we have
found while applying the previous hunk into account when looking for a
match with find_pos(), but dismissed that approach, because it would
sometimes work better but sometimes worse, depending on the difference
between the version the patch was created against and the version the
patch is being applied.

This does _not_ prevent misapplication of patches to a file that has many
similar looking blocks of lines and a preimage cannot identify which one
of them should be applied.  For that, we would need to scan beyond the
first match in find_pos(), and issue a warning (or error out).  That will
be a separate topic.

Limit file descriptors used by packs

Rather than using 'errno == EMFILE' after a failed open() call
to indicate the process is out of file descriptors and an LRU
pack window should be closed, place a hard upper limit on the
number of open packs based on the actual rlimit of the process.

By using a hard upper limit that is below the rlimit of the current
process it is not necessary to check for EMFILE on every single
fd-allocating system call.  Instead reserving 25 file descriptors
makes it safe to assume the system call won't fail due to being over
the filedescriptor limit.  Here 25 is chosen as a WAG, but considers
3 for stdin/stdout/stderr, and at least a few for other Git code
to operate on temporary files.  An additional 20 is reserved as it
is not known what the C library needs to perform other services on
Git's behalf, such as nsswitch or name resolution.

This fixes a case where running `git gc --auto` in a repository
with more than 1024 packs (but an rlimit of 1024 open fds) fails
due to the temporary output file not being able to allocate a
file descriptor.  The output file is opened by pack-objects after
object enumeration and delta compression are done, both of which
have already opened all of the packs and fully populated the file
descriptor table.

vcs-svn: teach line_buffer about temporary files

It can sometimes be useful to write information temporarily to file,
to read back later.  These functions allow a program to use the
line_buffer facilities when doing so.

It works like this:

 1. find a unique filename with buffer_tmpfile_init.
 2. rewind with buffer_tmpfile_rewind.  This returns a stdio
    handle for writing.
 3. when finished writing, declare so with
    buffer_tmpfile_prepare_to_read.  The return value indicates
    how many bytes were written.
 4. read whatever portion of the file is needed.
 5. if finished, remove the temporary file with buffer_deinit.
    otherwise, go back to step 2,

The svn support would use this to buffer the postimage from delta
application until the length is known and fast-import can receive
the resulting blob.

use this to read variable-length integers one byte at a time.

Underneath, it is fgetc, wrapped so the line_buffer library can

vcs-svn: add binary-safe read function

buffer_read_string works well for non line-oriented input except for
one problem: it does not tell the caller how many bytes were actually
written.  This means that unless one is very careful about checking
for errors (and eof) the calling program cannot tell the difference
between the string "foo" followed by an early end of file and the
string "foo\0bar\0baz".

So introduce a variant that reports the length, too, a thinner wrapper
around strbuf_fread.  Its result is written to a strbuf so the caller
does not need to keep track of the number of bytes read.

t0081 (line-buffer): add buffering tests

POSIX makes the behavior of read(2) from a pipe fairly clear: a read
from an empty pipe will block until there is data available and any
other read will not block, prefering to return a partial result.
Likewise, fread(3) and fgets(3) are clearly specified to act as
though implemented by calling fgetc(3) in a simple loop.  But the
buffering behavior of fgetc is less clear.

Luckily, no sane platform is going to implement fgetc by calling the
equivalent of read(2) more than once.  fgetc has to be able to
return without filling its buffer to preserve errno when errors are
encountered anyway.  So let's assume the simpler behavior (trust) but
add some tests to catch insane platforms that violate that when they
come (verify).

First check that fread can handle a 0-length read from an empty fifo.
Because open(O_RDONLY) blocks until the writing end is open, open the
writing end of the fifo in advance in a subshell.

Next try short inputs from a pipe that is not filled all the way.

Lastly (two tests) try very large inputs from a pipe that will not fit
in the relevant buffers.  The first of these tests reads a little
more than 8192 bytes, which is BUFSIZ (the size of stdio's buffers)
on this Linux machine.  The second reads a little over 64 KiB (the
pipe capacity on Linux) and is not run unless requested by setting
the GIT_REMOTE_SVN_TEST_BIG_FILES environment variable.

svn-fe's delta applier will use this to stream a delta from svnrdump
