On Cygwin, poll() reports POLLIN even for file descriptors that have
reached their end. This caused git upload-archive to be stuck in an
infinite loop, as it only looked at the POLLIN flag.
In addition to POLLIN, check if read() returned 0, which indicates
end-of-file, and keep looping only as long as at least one of the file
descriptors has input. This lets the following command finish on its
own when run in a git repository on Cygwin, instead of it getting stuck
after printing all file names:
$ git archive -v --remote . HEAD >/dev/null

Certain remote commands, when asked to do something in a
particular directory that was not actually a git repository,
would say "unable to chdir or not a git archive". The
"chdir" bit is an unnecessary detail, and the term "git
archive" is much less common these days than "git repository".
So let's switch them all to:
fatal: '%s' does not appear to be a git repository

MAX_EXTRA_ARGS is not used anymore, so remove it. MAX_ARGS is used only
in builtin-upload-archive.c, so define it there. Also report the actual
value we're comparing against when the number of args is too big.

Both archive and upload-archive have to parse command line arguments and
then call the archiver specific write function. Move the duplicate code
to a new function, write_archive().

Pass struct archiver and struct archiver_args explicitly to parse_archive_args
and remove the latter from the former. This allows us to get rid of struct
archiver_desc and simplifies the code a bit.

When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form. So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.
This patch makes git commands show the dash-less version.
For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh
generates a dash-less usage string now.

We have a number of badly checked read() calls. Often we are
expecting read() to read exactly the size we requested or fail, this
fails to handle interrupts or short reads. Add a read_in_full()
providing those semantics. Otherwise we at a minimum need to check
for EINTR and EAGAIN, where this is appropriate use xread().

This is a mechanical clean-up of the way *.c files include
system header files.
(1) sources under compat/, platform sha-1 implementations, and
xdelta code are exempt from the following rules;
(2) the first #include must be "git-compat-util.h" or one of
our own header file that includes it first (e.g. config.h,
builtin.h, pkt-line.h);
(3) system headers that are included in "git-compat-util.h"
need not be included in individual C source files.
(4) "git-compat-util.h" does not have to include subsystem
specific header files (e.g. expat.h).

The current code works like this: if others flags than POLLIN is
raised we assume that (a) something bad happened and the child died or
(b) the child has closed the pipe because it had no more data to send.
For the latter case, we assume wrongly that one call to
process_input() will empty the pipe. Indeed it reads only 16Ko of data
by call and the the pipe capacity can be larger than that (on current
Linux kernel, it is 65536 bytes). Therefore the child can write 32ko
of data, for example, and close the pipe. After that poll will return
POLLIN _and_ POLLHUP and the parent will read only 16ko of data.
This patch forces the parent to empty the pipe as soon as POLLIN is
raised and even if POLLHUP or something else is raised too.
Moreover, some implementations of poll might return POLLRDNORM flag
even if it is non standard.

Franck noticed that the code around polling and relaying messages
from the child process was quite bogus. Here is an attempt to
clean it up a bit, based on his patch:
- When POLLHUP is set, it goes ahead and reads the file
descriptor. Worse yet, it does not check the return value of
read() for errors when it does.
- When we processed one POLLIN, we should just go back and see
if any more data is available. We can check if the child is
still there when poll gave control back at us but without any
actual input.
[jc: with simplification suggested by Franck. ]

Using the refactored sideband code from existing upload-pack protocol,

This command implements the git archive protocol on the server
side. This command is not intended to be used by the end user.
Underlying git-archive command line options are sent over the
protocol from "git-archive --remote=...", just like upload-tar
currently does with "git-tar-tree=...".
As for "git-archive" command implementation, this new command
does not execute any existing "git-{tar,zip}-tree" but rely
on the archive API defined by "git-archive" patch. Hence we
get 2 good points:
- "git-archive" and "git-upload-archive" share all option
parsing code.
- All kind of git-upload-{tar,zip} can be deprecated.
