Nuke dead assignments and a dead function, from Michael W Bombardieri
using lint.

Add cvs_mkdir() for recursive directory creation on import, based on a
diff from Michael W Bombardieri in PR 6398.

Reduce variable/function name and whitespace differences between

Rename a bunch of variables and functions, removing the cvs_/rcs_
prefixes to reduce differences between cvs and rcs files.

completely kill the need for TMP_DIR when running checkout,
which gives us better performance among other things.

this is however disabled in a few cases:
1) whenever you run checkout over an existing tree (which acts as update)
2) whenever you specify -d or a module alias

we're planning on enabling this behaviour for case 2 in the future.

anoncvs sysadmins now love us even more.

New trigger framework that allows us to run the required scripts

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

more CVSROOT/modules stuff:

- support for -i flag:
Run "prog" on "cvs commit" from top-level of module.
- fix some memory leaks in modules.c
- pass the line number from cvs_read_config() towards the callbacks
so its easier to print out where it's going wrong, if it ever does.

Stripped off 'nb', which was (or was supposed to be) used to distinguish
between a named branch and a revision number supplied by -r. This can
be done easier in cvs_write_tagfile directly.

Added annotate support for local and remote repositories. Behaves like
GNU cvs but is a little faster.

Rework the way opencvs works in relation to files in the Attic/:

Previously, files in the 'Attic/' were linked into our filelist as being
'Attic/filename,v' this caused unneeded stress on certain functions
like cvs_file_classify() who had to do pointer voodoo to split out
the 'Attic/' part and do other very weird stuff to normalize the pathname
of these files.

Instead, we handle these files early in the start when we
build the fileslist in cvs_repository_getdir(). When encountering
the 'Attic/' directory, we recurse in it if required but instead of
using the 'Attic/' directory component as our base directory we stick
with the directory name where 'Attic/' resides in, resulting in the
correct filename while maintaining the correct RCSpath for the file.

This made the following things a lot easier:
(and in most cases actually fixed the below points)

- status with files in Attic/.
- checking out HEAD repositories with files in Attic/.
- checking out repositories with -rTAG.
- updating with -rTAG.

and as an added bonus the following now also works:

- correctly creating CVS/Tag in both local and remote mode thus
allowing update/status/and more to work correctly with the tagged tree.
(thanks to the correct handling of -rTAG cases).
- resetting tags with opencvs -A properly works too now.

This is a major step forward into the usability
of OpenCVS when it comes to maintaining multiple tagged trees, the next
logical step would be to fix commiting to branches.

enjoy you -stable cowards.

tested by myself, xsa, niallo and ckuethe

cvs_splitpath() isn't used anymore; from Tobias Stoeckmann.

make it look a little less chaotic.

add code which allows us to select revisions based upon
a string given by the user on the command line, much like
rcs_revision_select in OpenRCS.

this will be usefull for some commands.

- cvs_get_repository_path() now returns the full repository path for
the given argument.
- cvs_get_repository_name() returns the contents of CVS/Repository
to the caller.
- allow command callbacks to specify if our recursion code needs
to skip the directory or not.
- when checking for a admin directory, make sure it is in fact
a directory. if it is not we dont want to recurse inside.
