the section describing all the kinds of error message.

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.
git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3153
- All memory-related errors are now clear whether they are caused by
unaddressable or uninitialised memory. (Previously, writes were
clearly addressability errors, but reads could be either.) Mostly
done by replacing the 'isWrite' field in MAC_Error with 'isUnaddr'.
Also, mc_check_readable() now indicates not just if an error occurred,
but what kind of error (ie. addressability or definedness).
- Put machinery into place in the core to inform tools when registers
are being read by the core -- ie. a 'pre_reg_read' event. Most
notably, this facilitates syscall scalar arg definedness checking for
Memcheck. Currently this is only working for read(), write(), exit()
and exit_group(), but it will be extended as the syscalls are
overhauled as part of the arch-abstraction work.
A consequence of this is that the ParamErr messages have changed. This:
Syscall param write(buf) contains uninitialised byte(s)
now means that the pointer 'buf' is partially undefined. If the memory
pointed to by 'buf' is partially undefined or unaddressable, it says one of:
Syscall param write(buf) points to uninitialised byte(s)
Syscall param write(buf) points to unaddressable byte(s)
The docs have been updated accordingly.
I also added a couple of regression tests.
These two change sare notable for being the first improvements to
Memcheck's checking/errors in a long time.
I also folded mc_clientreqs.c into mc_main.c, which saves exporting a
whole bunch of things that are not used anywhere else.

- Added include/x86-linux/ and include/linux/ subdirectories, with Makefile.am
files.
- Overhauled the definitions of kernel types. include/vg_kerneliface.h is now
three files, include/linux/vki.h, include/x86-linux/vki_arch.h, and
include/x86-linux/vki_arch_posixtypes.h. These files separate the
common/Linux and x86/Linux parts cleanly. All code is copied verbatim from
the relevant kernel headers, except that VKI_/vki_ prefixes are added as
necessary to distinguish them from glibc types. (This is done consistently,
unlike previously when some types did not have the prefixes.)
All code is clearly marked to show which particular header file it came from,
and the Linux version used. (I used 2.6.8.1, the most recent stable release,
for all of them.)
A few of the types changed; this is because they changed between the older
versions of Linux and the current 2.6.8.1. I checked that all these changes
were ok with respect to backwards compatibility for our purposes.
- vg_unsafe.h has been removed; we are no longer including any kernel headers,
as we have our own copies for everything. This is because installed kernel
headers are not reliable, and often cause compilation problems. (bug
#92420 is a recent example)
- Removed some no-longer-needed header-presence tests from configure.in.
- Some code in the rest of Valgrind was changed to account for some slight
changes in the names of our VKI_/vki_ kernel constants and types.
- Updated README_MISSING_SYSCALL_OR_IOCTL accordingly.
- Fixed off-by-one error with VKI_GDT_ENTRY_TLS_MAX (merged from stable branch)
The end result is that the kernel types situation should be much clearer, and
similar files can be created relatively easily for other architectures as
necessary.

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.

valgrind.h. Although these requests are not implemented by the core, they can
be implemented by skins that track heap blocks, eg. Memcheck, Annelid, Massif.
This is in preparation for committing Massif to the repository.
I think I managed to make the change in a binary-compatible way. The only
inconvenience for users is that if they have a client program compiled with the
old requests in, Valgrind will abort with an explanatory message that tells
them to recompile. Once they've done that (no changes to their program are
required), it works again.
I even updated the docs.

requests from the Memcheck requests and putting the descriptions in the
appropriate parts of the docs.
Removed the __VALGRIND_SOME_SKIN_H test -- it was designed to prevent people
#including valgrind.h when they probably want memcheck.h, but it's actually a
reasonable thing to do to #include valgrind.h alone, because there are some
requests in valgrind.h.
Removed references to VALGRIND_MAKE_NOACCESS_STACK from the docs, as it doesn't
exist in the implementation.
Fixed a few other minor things.

neatens other things up.
Also, it adds the --gen-suppressions option for automatically generating
suppressions for each error.
Note that it changes the core/skin interface:
SK_(dup_extra_and_update)() is replaced by SK_(update_extra)(), and
SK_(get_error_name)() and SK_(print_extra_suppression_info)() are added.

details
-----------------------------------------------------------------------------
Removed ac_common.c -- it just #included another .c file; moved the
#include into ac_main.c.
Introduced "mac_" prefixes for files shared between Addrcheck and Memcheck,
to make it clearer which code is shared. Also using a "MAC_" prefix for
functions and variables and types that are shared. Addrcheck doesn't see
the "MC_" prefix at all.
Factored out almost-identical mc_describe_addr() and describe_addr()
(AddrCheck's version) into MAC_(describe_addr)().
Got rid of the "pp_ExeContext" closure passed to SK_(pp_SkinError)(), it
wasn't really necessary.
Introduced MAC_(pp_shared_SkinError)() for the error printing code shared by
Addrcheck and Memcheck. Fixed some bogus stuff in Addrcheck error messages
about "uninitialised bytes" (there because of an imperfect conversion from
Memcheck).
Moved the leak checker out of core (vg_memory.c), into mac_leakcheck.c.
- This meant the hacky way of recording Leak errors, which was different to
normal errors, could be changed to something better: introduced a
function VG_(unique_error)(), which unlike VG_(maybe_record_error)() just
prints the error (unless suppressed) but doesn't record it. Used for
leaks; a much better solution all round as it allowed me to remove a lot
of almost-identical code from leak handling (is_suppressible_leak(),
leaksupp_matches_callers()).
- As part of this, changed the horrible SK_(dup_extra_and_update) into the
slightly less horrible SK_(update_extra), which returns the size of the
`extra' part for the core to duplicate.
- Also renamed it from VG_(generic_detect_memory_leaks)() to
MAC_(do_detect_memory_leaks). In making the code nicer w.r.t suppressions
and error reporting, I tied it a bit more closely to Memcheck/Addrcheck,
and got rid of some of the args. It's not really "generic" any more, but
then it never really was. (This could be undone, but there doesn't seem
to be much point.)
STREQ and STREQN were #defined in several places, and in two different ways.
Made global macros VG_STREQ, VG_CLO_STREQ and VG_CLO_STREQN in vg_skin.h.
Added the --gen-suppressions code. This required adding the functions
SK_(get_error_name)() and SK_(print_extra_suppression_info)() for skins that
use the error handling need.
Added documentation for --gen-suppressions, and fixed some other minor document
problems.
Various other minor related changes too.
