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:

To give OPT_FILENAME the prefix, we pass the prefix to parse_options()
which passes the prefix to parse_options_start() which sets the prefix
member of parse_opts_ctx accordingly. If there isn't a prefix in the
calling context, passing NULL will suffice.

Programs that use git_config need to find the global configuration.
When runtime prefix computation is enabled, this requires that
git_extract_argv0_path() is called early in the program's main().
This commit adds the necessary calls.

Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

The new option allows the contents to be hashed as is, ignoring any input
filter that would have been chosen by the attributes mechanism.
This option is incompatible with --path and --stdin-paths options.

The --path option allows us to pretend as if the contents being hashed
came from the specified path, and affects which input filter is used via
the attributes mechanism. This is useful for hashing a temporary file
whose name is different from the path that is meant to have the hashed
contents.

index_fd can now work with file descriptors that are not normal files
but any readable file. If the given file descriptor is a regular file
then mmap() is used; for other files, strbuf_read is used.
The path parameter, which has been used as hint for filters, can be
NULL now to indicate that the file should be hashed literally without
any filter.
The index_pipe function is removed as redundant.

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.

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 hash-object used to process the --stdin command line argument
before reading subsequent arguments. This caused 'git hash-object
--stdin -w' to fail to actually write the object into the
database, while '-w --stdin' properly did. Now git hash-object
first reads all arguments, and then processes them.
This regresses one insane use case. git hash-object used to allow
multiple --stdin arguments on the command line:
$ git hash-object --stdin --stdin
foo
^D
bar
^D
Now git hash-object errors out if --stdin is given more than once.

It was cumbersome to feed hash-object the file '-t' (you could
have said "./-t", though). Teach it '--' that terminates the
option list, like everybody else. There is no way to extract
usage string from the command either, so teach it "--help" as
well.

This patch makes the first half of write_sha1_file() and
index_fd() externally visible, to allow callers to compute the
object ID without actually storing it in the object database.
[JC demangled the whitespaces himself because he liked the patch
so much, and reworked the interface to index_fd() slightly,
taking suggestion from Linus and of his own.]
