so much so that the file is now 280 lines shorter. This despite me also adding
support for LOOP{E,NE} (thanks to Abhijit Menon-Sen). Also added support for
CMPS[lw], which was missing. Adding more REP-prefix instructions in the future
will now be much easier.
As part of this, I moved the D-flag fetch outside of the REP loops. This might
make programs that use REP prefixes a lot go faster.

signals, just used internally. Updated one regtest accordingly.

the places that normal users will see:
- command line: --tool=foo (although --skin=foo still works)
- docs: removed all traces (included renaming coregrind_skins.html to
coregrind_tools.html)
- in the usage messages
- in error messages
Also did in in some places that I judged were unlikely to cause clashes with
existing workspaces:
- in the header comments of many files (eg. "This file is part of Memcheck, a
Valgrind tool for...")
- in the regtests script
- in the .supp files
- in AUTHORS
- in README_MISSING_SYSCALL_OR_IOCTL
Also update the AUTHORS file to mention Jeremy.

mess. Pulled the symbol table reading bit out of vg_read_lib_symbols() into
read_symtab(), in the process removing the awful twice-only loop used to read
the symbol table and the dynamic symbol table. Factored out the code used to
find sections of interest (eg. .strtab, .symtab, .stabs, .plt, etc), replacing
nine (yes, nine) individual and slightly differing searches.
It's now much easier to understand, 132 lines shorter, and provides a better
base for easily doing more complicated debug stuff, eg. when we start reading
in all the debugging info (such as .debug_info for dwarf2).

option --show-below-main is on. It's on by default. It also affects
suppressions generated with --gen-suppressions=yes. Updated reg tests
accordingly.
Also updated docs for this. And added some missing command-line args to docs.
Also compartmentalised the options a little in the docs, and rearranged the
order of options in the usage message, in anticipation of a bigger
rearrangement that will be necessary soon -- to distinguish options used by all
skins from those used by error-checking skins, to skin-specific ones.

If the proxyLWP for a thread got a signal just as we were sending the
syscall request to it, then we would end up running the syscall twice.
The fix is to not check the results pipe while sending the syscall request
- wait until we're in a better state for handling signals (the deadlock
the results-read was supposed to avoid cannot actually happen).
Related to that, if we're delivering a signal to a thread, and that thread
is currently waiting for a syscall to complete, make sure we collect the
syscall results before entering the signal handler (otherwise we may end
up bogusly trying to restart the syscall by moving EIP back, even though
it now points to the signal handler rather than the syscall instruction)
This change also adds an assertion to VG_(restart_syscall) to make sure
we were actually restarting a syscall and not just randomly changing EIP
(this found the problem above).
Also, make set/getitimer run in the proxyLWP context, so that they
modify/read the proxyLWP's timers rather than the schedluer LWP's timers.

requests to allow client code to print messages through Valgrind's
logging mechanism. The new requests are:
VALGRIND_PRINTF - do a normal printf (prefixed with **PID**)
VALGRIND_PRINTF_BACKTRACE - do a printf with stack trace
VALGRIND_INTERNAL_PRINTF - printf, but for internal use (prefixed with ==PID==)
VALGRIND_INTERNAL_PRINTF_BACKTRACE - as above, with backtrace
