git_config() only had a function parameter, but no callback data
parameter. This assumes that all callback functions only modify
global variables.
With this patch, every callback gets a void * parameter, and it is hoped
that this will help the libification effort.

git var works fine even when not called in a git repository. So
don't require it.
This will make it possible to remove this pre-condition for some
other git commands as well.

An earlier fix to the said commit was incomplete; it mixed up the
meaning of the flag parameter passed to the internal fmt_ident()
function, so this corrects it.
git_author_info() and git_committer_info() can be told to issue a
warning when no usable user information is found, and optionally can be
told to error out. Operations that actually use the information to
record a new commit or a tag will still error out, but the caller to
leave reflog record will just silently use bogus user information.
Not warning on misconfigured user information while writing a reflog
entry is somewhat debatable, but it is probably nicer to the users to
silently let it pass, because the only information you are losing is who
checked out the branch.
* git_author_info() and git_committer_info() used to take 1 (positive
int) to error out with a warning on misconfiguration; this is now
signalled with a symbolic constant IDENT_ERROR_ON_NO_NAME.
* These functions used to take -1 (negative int) to warn but continue;
this is now signalled with a symbolic constant IDENT_WARN_ON_NO_NAME.
* fmt_ident() function implements the above error reporting behaviour
common to git_author_info() and git_committer_info(). A symbolic
constant IDENT_NO_DATE can be or'ed in to the flag parameter to make
it return only the "Name <email@address.xz>".
* fmt_name() is a thin wrapper around fmt_ident() that always passes
IDENT_ERROR_ON_NO_NAME and IDENT_NO_DATE.

This uses "git-apply --whitespace=strip" to fix whitespace errors that have
crept in to our source files over time. There are a few files that need
to have trailing whitespaces (most notably, test vectors). The results
still passes the test, and build result in Documentation/ area is unchanged.

Back when only handful commands that created commit and tag were
the only users of committer identity information, it made sense
to explicitly call setup_ident() to pre-fill the default value
from the gecos information. But it is much simpler for programs
to make the call automatic when get_ident() is called these days,
since many more programs want to use the information when updating
the reflog.

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).

Previous one warned people upfront to encourage fixing their
environment early, but some people just use repositories and git
tools read-only without making any changes, and in such a case
there is not much point insisting on them having a usable ident.
This round attempts to move the error until either "git-var"
asks for the ident explicitly or "commit-tree" wants to use it.

var.c::git_var read function did not have to return writable
strings; make it and the functions it points at return const char *
instead.
ident.c::get_ident() did not need to be global, so make it
static.

This starts using the "user.name" and "user.email" config variables if
they exist as the default name and email when committing. This means
that you don't have to use the GIT_COMMITTER_EMAIL environment variable
to override your email - you can just edit the config file instead.
The patch looks bigger than it is because it makes the default name and
email information non-static and renames it appropriately. And it moves
the common git environment variables into a new library file, so that
you can link against libgit.a and get the git environment without having
to link in zlib and libcrypt.
In short, most of it is renaming and moving, the real change core is
just a few new lines in "git_default_config()" that copies the user
config values to the new base.
It also changes "git-var -l" to list the config variables.

Sharing code between shell scripts and C is a challenge. The program
git-var allows us to have a set of named values that a shell script can
interrogate and a normal C program can simply call the functions that
compute them. Allowing sharing when computing plain test values.
