Commits, trees and tags have structure. Don't let users feed git
with malformed ones. Sooner or later git will die() when
encountering them.

Note that this patch does not check semantics. A tree that points
to non-existent objects is perfectly OK (and should be so, users
may choose to add commit first, then its associated tree for example).

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.

Because the file name given to stdin did not exist, git hash-object
fails to open it and exits with non-zero error code.

Thus the test may pass even if there is an error in argument checking.

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.
