Memcheck, replacing the 9-bits-per-byte shadow memory representation to a
2-bits-per-byte representation (with possibly a little more on the side) by
taking advantage of the fact that extremely few memory bytes are partially
defined.
For the SPEC2k benchmarks with "test" inputs, this speeds up Memcheck by a
(geometric mean) factor of 1.20, and reduces the size of shadow memory by a
(geometric mean) factor of 4.26.
At the same time, Addrcheck is removed. It hadn't worked for quite some
time, and with these improvements in Memcheck its raisons-d'etre have
shrivelled so much that it's not worth the effort to keep around. Hooray!
Nb: this code hasn't been tested on PPC. If things go wrong, look first in
the fast stack-handling functions (eg. mc_new_mem_stack_160,
MC_(helperc_MAKE_STACK_UNINIT)).

- removed a reference to cachegrind dot org from mc-tech-docs.xml
- in an effort to simplify future borked links, replaced all valgrind
website urls with entities so now we just have to change one string.
- new stylesheet to create the docs to 'fit' into the website
- added build rules 'make website-docs' + make download-docs
to /docs/Makefile.am

up to date with reality. Please give this a proofread.
I ran out of steam at memcheck/docs/mc_techdocs.html, which is even more
hopelessly out of date. I will note that cacheprof.org is some kind of
dental insurance company now...

converted by Donna. Hooked it into the build system so they are only
built when specifically asked for, and when doing "make dist".
They're not perfect; in particular, there are the following problems:
- The plain-text FAQ should be built from FAQ.xml, but this is not
currently done. (The text FAQ has been left in for now.)
- The PS/PDF building doesn't work -- it fails with an incomprehensible
error message which I haven't yet deciphered.
Nonetheless, I'm putting it in so others can see it.
