Remove xfree(), like already done for RCS. From Michael W Bombardieri,
ok mmcc

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible. Annotate <sys/param.h> lines with their current reasons. Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution. These are the files confirmed
through binary verification.
ok guenther, millert, doug (helped with the verification protocol)

unsigned char for ctype. ok deraadt

Remove a silly XXX for a bit of code that is only used once - no value
in making it a function. From Michael W Bombardieri.

Nuke some unused variables and remove an unnecessary call to dirname().

From Michael W Bombardieri via ray@.

Reduce variable/function name and whitespace differences between
cvs/rcs.

OK xsa zinovik

only pass the real $var to expand_vars() instead of the entire
line, this way commitinfo and stuff works again.

found by myself the hard way, fix by tobias@
who's not around to commit.

Support for variable expansion in trigger files added.

ok joris

If parsing of a command in one of the trigger files fails, treat this as an
error instead of ignoring it.

ok joris

Plug memory and file descriptor leaks, diff by Jonathan Armani.

ok joris

Regular expressions to match repository are allowed to have % in front.
Diff by Jonathan Armani.

spacing

files that have been removed should be passing "NONE" to scripts
as their new revision, so they can be picked up as being removed.

We have a cvs_buf_puts implementation now, also use cvs_buf_putc instead
of cvs_buf_append where appropiate.

ok joris

If we encounter an error during expanding line of a trigger file, print an
actually useful error message.

ok joris

append "- Imported sources" for imports.

newly added directories need "- New directory" to be passed to the
loginfo script.

ok tobias@

pass the basename(3) for file_path to the script, so we do not get
weird double modules names in the logs;

newly added files should pass "NONE" for their initial revision, unbreaks
more scripts that depend on this.

loginfo allows 't' as well - unbreaks certain loginfo scripts.

missing header

style

New trigger framework that allows us to run the required scripts
defined in CVSROOT/commitinfo and CVSROOT/loginfo and so on.

This enables the use of log_accum2 and all that other nice stuff we like.

This was mostly written by Jonathan Armani with help from tobias@ and myself.
