Brandon Casey 1630726e84 abspath.c: move declaration of 'len' into inner block and use appropriate type
The 'len' variable was declared at the beginning of the make_absolute_path
function and also in an inner 'if' block which masked the outer declaration.
It is only used in two 'if' blocks, so remove the outer declaration and
make a new declaration inside the other 'if' block that uses 'len'.

Thomas Rast 0721c314a5 Use die_errno() instead of die() when checking syscalls
Lots of die() calls did not actually report the kind of error, which
can leave the user confused as to the real problem.  Use die_errno()
where we check a system/library call that sets errno on failure, or
one of the following that wrap such calls:

  Function              Passes on error from
  --------              --------------------
  odb_pack_keep         open
  read_ancestry         fopen
  read_in_full          xread
  strbuf_read           xread
  strbuf_read_file      open or strbuf_read_file
  strbuf_readlink       readlink
  write_in_full         xwrite

Junio C Hamano 90b4a71c49 is_directory(): a generic helper function
A simple "grep -e stat --and -e S_ISDIR" revealed there are many
open-coded implementations of this function.

Johannes Sixt 10c4c881c4 Allow add_path() to add non-existent directories to the path
This function had used make_absolute_path(); but this function dies if
the directory that contains the entry whose relative path was supplied in
the argument does not exist. This is a problem if the argument is, for
example, "../libexec/git-core", and that "../libexec" does not exist.

Since the resolution of symbolic links is not required for elements in
PATH, we can fall back to using make_nonrelative_path(), which simply
prepends $PWD to the path.

We have to move make_nonrelative_path() alongside make_absolute_path() in
abspath.c so that git-shell can be linked. See 5b8e6f85f.

Dmitry Potapov 5b8e6f85f9 shrink git-shell by avoiding redundant dependencies
A lot of modules that have nothing to do with git-shell functionality
were linked in, bloating git-shell more than 8 times.

This patch cuts off redundant dependencies by:
1. providing stubs for three functions that make no sense for git-shell;
2. moving quote_path_fully from environment.c to quote.c to make the
   later self sufficient;
3. moving make_absolute_path into a new separate file.

The following numbers have been received with the default optimization
settings on master using GCC 4.1.2:

Before:
   text    data     bss     dec     hex filename
 143915    1348   93168  238431   3a35f git-shell

After:
   text    data     bss     dec     hex filename
  17670     788    8232   26690    6842 git-shell
