Based on patch from Ralf Wildenhues <Ralf.Wildenhues@gmx.de>.

Valgrind's dependency on the dynamic linker for getting started, and
instead takes things into its own hands.
This checkin doesn't add much in the way of new functionality, but it
is the basis for all future work on Valgrind. It allows us much more
flexibility in implementation, and well as increasing the reliability
of Valgrind by protecting it more from its clients.
This patch requires some changes to tools to update them to the changes
in the tool API, but they are straightforward. See the posting "Heads
up: Full Virtualization" on valgrind-developers for a more complete
description of this change and its effects on you.

- changed deprecated INCLUDES variable to AM_CPPFLAGS
- moved the -DVG_LIBDIR definition from AM_CFLAGS into AM_CPPFLAGS
- generally neatened them up a bit -- removed old commented out stuff, fixed a
couple of other minor things
Everything works for me, hopefully it won't break things for anyone else...

If this breaks something, please mail me first instead of reverting.
Thank you.

- added some missing SUBDIRS variables
- removed unnecessary coregrind/demangle/ from some INCLUDES lists

- changed lots of Makefile.am files
- changed configure.in
- changed lots of #include lines for changed file names
- changed lots of file headers n footers for changed file names
- changed vg_regtest to handle new directory structure -- recursively
traverses subdirectories for .vgtest test files

automatic cache configuration detection using the CPUID instruction.
This can be overridden from the command-line if necessary.
vg_include.h:
- added the cache_t type and UNDEFINED_CACHE macro
- added command line args (of type cache_t) allowing manual override of
I1/D1/L2 configuration
- added log2(), which is generally useful
vg_main.c, valgrind.in, cachegrind.in:
- added handling of the new --{I1,D1,L2}=<size>,<assoc>,<line_size>
options
vg_cachesim.c:
- lots of stuff for auto-detecting cache configuration with CPUID.
Only handles Intel and AMD chips at the moment, and possibly not all of
them. Falls back onto defaults if anything goes wrong, and the configs
can be manually overridden from the command line anyway.
- now not printing cache summary stats if verbosity == 0. Still writing
cachegrind.out, though.
vg_cachesim_gen.c:
- new file containing stuff shared by the I1/D1/L2 simulations
vg_cachesim_{I1,D1,L2}:
- removed most of it; each now just calls a macro defined in
vg_cachesim_gen.c
vg_cachegen:
- has been cvs removed as it is no longer needed.
Makefile.am:
- added vg_cachesim_gen.c
- removed vg_cachegen
configure.in:
- removed vg_cachegen

as well as LD_PRELOAD, so as to make our libpthread.so go out of scope
when a child which we don't want to trace, is exec'd. Otherwise the
child can wind up being connected to our libpthread.so but not to
valgrind.so, which is an unworkable combination; you have to be connected
to both or neither.

with the new vg_libpthread.vs linker script. Problem is that builds
where builddir != srcdir don't work now. Don't know how to fix.

- vg_cachesim.c
- vg_cachesim_{I1,D1,L2}.c
- vg_annotate.in
- vg_cachegen.in
Changes to existing files:
- valgrind/valgrind.in, added option:
--cachesim=no|yes [no]
- Makefile/Makefile.am:
* added vg_cachesim.c to valgrind_so_SOURCES var
* added vg_cachesim_I1.c, vg_cachesim_D1.c, vg_cachesim_L2.c to
noinst_HEADERS var
* added vg_annotate, vg_cachegen to 'bin_SCRIPTS' var, and added empty
targets for them
- vg_main.c:
* added two offsets for cache sim functions (put in positions 17a,17b)
* added option handling (detection of --cachesim=yes which turns off of
--instrument);
* added calls to cachesim initialisation/finalisation functions
- vg_mylibc: added some system call wrappers (for chmod, open_write, etc) for
file writing
- vg_symtab2.c:
* allow it to read symbols if either of --instrument or --cachesim is
used
* made vg_symtab2.c:vg_what_{line,fn}_is_this extern, renaming it as
VG_(what_line_is_this) (and added to vg_include.h)
* completely rewrote the read loop in vg_read_lib_symbols, fixing
several bugs. Much better now, although probably not perfect. It's
also relatively fragile -- I'm using the "die immediately if anything
unexpected happens" approach.
- vg_to_ucode.c:
* in VG_(disBB), patching in x86 instruction size into extra4b field of
JMP instructions at the end of basic blocks if --cachesim=yes.
Shifted things around to do this; also had to fiddle around with
single-step stuff to get this to work, by not sticking extra JMPs on
the end of the single-instruction block if there was already one
there (to avoid breaking an assertion in vg_cachesim.c). Did a
similar thing to avoid an extra JMP on huge basic blocks that are
split.
- vg_translate.c:
* if --cachesim=yes call the cachesim instrumentation phase
* made some functions extern and renamed:
allocCodeBlock() --> VG_(allocCodeBlock)()
freeCodeBlock() --> VG_(freeCodeBlock)()
copyUInstr() --> VG_(copyUInstr)()
(added to vg_include.h too)
- vg_include.c: declared
* cachesim offsets
* exports of vg_cachesim.c
* added four new profiling events (increasing VGP_M_CCS to 24 -- I kept
the spare ones)
* added comment about UInstr.extra4b field being used for instr size in
JMPs for cache simulation
- docs/manual.html:
* Added --cachesim option to section 2.5.
* Added cache profiling stuff as section 7.

by the real libpthread.so. In the process fix a bunch of stuff, including
adding thread-specific h_errno and resolver state storage. This fixes
licq crashing at startup.

- Get rid of -Werror; it breaks to many people's builds. It can be
passed in with make variable WERROR if needed.

about doesn't support it
- readd -Werror
- move setting of CFLAGS to the Makefile instead of the configure
script, to avoid that the custom flags we use screw up configure checks

file vg_libpthread.so.0.c. Now:
* libpthread.so is built as just-another-so, like valgrind.so and
valgrinq.so.
* there is a new dummy target libpthread.so.0 which is build just
by a symlink.
Unfortunately for some reason, when the .so.0 is installed, it gets
a complete copy rather than just the symlink being copied. But it
works, at least.

for pthread_* support. Major changes:
* Valgrind now contains a (skeletal!) user-space pthreads
implementation. The exciting bits are in new file vg_scheduler.c.
This contains thread management and scheduling, including nasty crud
to do with making some syscalls (read,write,nanosleep) nonblocking.
Also implementation of pthread_ functions: create join
mutex_{create,destroy,lock,unlock} and cancel.
* As a side effect of the above, major improvements to signal handling
and to the client-request machinery. This is now used to intercept
malloc/free etc too; the hacky way this is done before is gone.
Another side effect is that vg_dispatch.S is greatly simplified.
Also, the horrible hacks to do with delivering signals to threads
blocked in syscalls are gone, since the new mechanisms cover this case
easily.
