Add dmalloc debug library facility.
Add patches for dmalloc.
Ignore the generated config/debug.in

Really use local copy first in case it does not have the same extension as the downloadable tarball.

Remove even more documentation.

Reverting to uClibc-0.9.28.3, as 0.9.29 spawns incorrect bits/sysnum.h (needs a xgcc first!).

Bah, forgot to ci CREDITS...

Patches for glibc-2.5, courtesy of "Robert P. J. Day" <rpjday@mindspring.com>

Make the debug config menu a generated file.
Add a uClibc-0.9.29 patch directory with one patch (from me!).
Update the armeb-unknown-linux-uclibc sample to uClibc-0.9.29.
Some eyecandy in the gdb build process.

Debug facilities:
- add a framework to easily add new ones
- add gdb as a first debug facility
- add patches for gdb
After the kernel checked its installed headers, clean up the mess of .checked.* files.
Reorder scripts/crosstool.sh:
- dump the configuration early
- renice early
- get info about build system early, when setting up the environment
- when in cross or native, the host tools are those of the build system, and only in this case
- elapsed time calculations moved to scripts/functions
Remove handling of the color: it's gone once and for all.
Update tools/addToolVersion.sh:
- handle debug facilities
- commonalise some code
- remove dead tools (cygwin, tcc)
Point to my address for bug reports.

Move the whole threading ;odel choice out of glibc and into the generic C library options: even uClibc may have NPTL at one point in the (hopefully near) future.
Mark the progress bar as being CPU-intensive.
Little style fix to the core C compiler build step.

Quiet some messages from the configurators. We don't need them.
