d6b40a390d Fixed up the log file mess throughout, including the docs. This killed
--log-file-qualifier and --log-file-exactly.

Updated NEWS some in preparation for 3.3.0.

9101880b1f Update documents in preparation for 3.3.0, and restructure them
somewhat to move less relevant material out of the way to some extent.
The main changes are:

* Update date and version info

* Mention other tools in the quick-start guide

* Document --child-silent-after-fork

* Rearrange order of sections in the Valgrind Core chapter, to move
  advanced stuff (client requests) to the end, and compact stuff
  relevant to the majority of users towards the front

* Move MPI debugging stuff from the Core manual (a nonsensical place
  for it) to the Memcheck chapter

* Update the manual's introductory chapter a bit

* Connect up new tech docs summary page, and disconnect old and
  very out of date valgrind/memcheck tech docs

* Add section tags to the Cachegrind manual, to stop xsltproc
  complaining about their absence

b91b51b42b Merge (from 3.2 branch) r6743 (Edit the manual to bring it up to date
and make some of the wording a bit more professional sounding.)

e16417ddf7 Add branch-misprediction profiling to Cachegrind. When the (new) flag
--branch-sim=yes is specified, Cachegrind simulates a simple indirect
branch predictor and a conditional branch predictor.  The latter
considers both the branch instruction's address and the behaviour of
the last few conditional branches.  Return stack prediction is not
modelled.

The new counted events are: conditional branches (Bc), mispredicted
conditional branches (Bcm), indirect branches (Bi) and mispredicted
indirect branches (Bim).  Postprocessing tools (cg_annotate, cg_merge)
handle the new events as you would expect.  Note that branch
simulation is not enabled by default as it gives a 20%-25% slowdown,
so you need to ask for it explicitly using --branch-sim=yes.

and associated documentation.

5748ebe527 Add a new flag --cachegrind-log-file to cg_annotate, which tells it
precisely the name of the profile data file it should use (instead of
assuming cachegrind.out.<pid> where <pid> is specified by the --<pid>
flag).  The old mechanism is still supported though.

1e55d37448 * Add new flag --cachegrind-out-file to specify the output file
basename to be something other than "cachegrind.out".

* Observe the core-supplied --log-file-qualifier, if specified,
  in creation of output file names.

* To make the above work, move most of the stuff in cg_pre_clo_init
  into cg_post_clo_init, so that the core's determination of the
  log file qualifier, if any, is done by the time cachegrind comes
  to process its arguments.

525ca8b1ee Removed the file format description from cg_annotate.in, because it's in the
Cachegrind docs.

Removed the Cachegrind tech docs, because they're so out of date to be
useless.  My PhD dissertation gives a much better description of how
Cachegrind works.  (I mentioned this in the Cachegrind user manual.)  The
only still-useful part of Cachegrind's tech docs, the output file format
description, I moved into the Cachegrind user manual.

7a75a9f583 Overhauled the docs. Removed all the HTML files, put in XML files as
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.
