A common scenario is to create a new branch and push it (checkout -b &&
push [--set-upstream]). In this case, the user was getting "The current
branch %s has no upstream branch.", which doesn't help much.
Provide the user a command to push the current branch. To avoid the
situation in the future, suggest --set-upstream.
While we're there, also improve the error message in the "detached HEAD"
case. We mention explicitly "detached HEAD" since this is the keyword to
look for in documentations.

The formerly implemented algorithm behaved differently to
remote.c:remote_get() at least for remotes that contain a slash. While the
former just assumes a/b is a path the latter checks the config for
remote."a/b" first which is more reasonable.
This removes the last user of git-parse-remote.sh:get_data_source(), so
this function is removed.

rerere forget is a destructive command. When invoked without a path, it
operates on the current directory, potentially deleting many recorded
conflict resolutions.
To make the command safer, a path must be specified as of git 1.8.0. Until
then, give users time to write 'git rerere forget .' if they really mean
the entire current directory.

If a pack file is small enough that its entire contents fits within
one mmap window, mmap the file and then immediately close its file
descriptor. This reduces the number of file descriptors that are
needed to read from repositories with many tiny pack files, such
as one that has received 1000 pushes (and created 1000 small pack
files) since its last repack.

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.

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.

buffer_read_char can be used in place of buffer_read_string(1) to
avoid consuming valuable static buffer space. The delta applier will
use this to read variable-length integers one byte at a time.
Underneath, it is fgetc, wrapped so the line_buffer library can
maintain its role as gatekeeper of input.
Later it might be worth checking if fgetc_unlocked is faster ---
most line_buffer functions are not thread-safe anyway.

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.

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.

Collect the line_buffer state in a newly public line_buffer struct.
Callers can use multiple line_buffers to manage input from multiple
files at a time.
svn-fe's delta applier will use this to stream a delta from svnrdump
and the preimage it applies to from fast-import at the same time.
The tests don't take advantage of the new features, but I think that's
okay. It is easier to find lingering examples of nonreentrant code by
searching for "static" in line_buffer.c.
