    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'.

    Use die_errno() instead of die() when checking syscalls

    trast authored gitster committed
    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:

    is_directory(): a generic helper function

    gitster authored
    A simple "grep -e stat --and -e S_ISDIR" revealed there are many
    open-coded implementations of this function.

    Allow add_path() to add non-existent directories to the path

    Johannes Sixt authored gitster committed
    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 5b8e6f8.

    shrink git-shell by avoiding redundant dependencies

    dmpot authored gitster committed
    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:
