Do our own ctype.h, just to get the sane semantics: we want locale-independence, _and_ we want the right signed behaviour. Plus we only use a very small subset of ctype.h anyway (isspace, isalpha, isdigit and isalnum). Signed-off-by: NJunio C Hamano <junkio@cox.net>

Symbolic refs are understood by resolve_ref(), so existing read_ref() users will automatically understand them as well. Signed-off-by: NJunio C Hamano <junio@twinsun.com>

A symbolic ref is a regular file whose contents is "ref:", followed by optional leading whitespaces, followed by a GIT_DIR relative pathname, followed by optional trailing whitespaces (the optional whitespaces are unconditionally removed, so you cannot have leading nor trailing whitespaces). This can be used in place of a traditional symbolic link .git/HEAD that usually points at "refs/heads/master". You can instead have a regular file .git/HEAD whose contents is "ref: refs/heads/master". [jc: currently the code does not enforce the symbolic ref to begin with refs/, unlike the symbolic link case. It may be worthwhile to require either case to begin with refs/ and not have any /./ nor /../ in them.] Signed-off-by: NJunio C Hamano <junkio@cox.net>

This is a careful version of the script stuff that currently just blindly writes HEAD with a new value. You can use git-update-ref HEAD <newhead> or git-update-ref HEAD <newhead> <oldhead> where the latter version verifies that the old value of HEAD matches oldhead. It basically allows a "ref" file to be a symbolic pointer to another ref file by starting with the four-byte header sequence of "ref:". More importantly, it allows the update of a ref file to follow these symbolic pointers, whether they are symlinks or these "regular file symbolic refs". NOTE! It follows _real_ symlinks only if they start with "refs/": otherwise it will just try to read them and update them as a regular file (ie it will allow the filesystem to follow them, but will overwrite such a symlink to somewhere else with a regular filename). In general, using git-update-ref HEAD "$head" should be a _lot_ safer than doing echo "$head" > "$GIT_DIR/HEAD" both from a symlink following standpoint _and_ an error checking standpoint. The "refs/" rule for symlinks means that symlinks that point to "outside" the tree are safe: they'll be followed for reading but not for writing (so we'll never write through a ref symlink to some other tree, if you have copied a whole archive by creating a symlink tree).
