(1) In r14664 VG_(get_fnname_if_entry) was changed to always
return a function name, even if that function was *not* an
entry. That broke callgrind and was also confusing because
it contradicts what "get_fnname_if_entry" suggests.
(2) In r14189 a function call was removed because it was considered
redundant which it was not.
Both bugs were hunted down by Joseph Weidendorfer.

Assorted fixes in exp-bbv to eliminate a few buffers.
Implement a suggestion found in the massif source, namely to add the
equivalent of fprintf to m_libcprint. Good suggestion. Thusly
- VgFile: similar to FILE; buffered output, 8k buffer
- VG_(fopen): similar to fopen, but with arguments as in VG_(open)
- VG_(fprintf) and VG_(vfprintf): like [v]fprintf with VgFile 1at argument
- VG_(fclose)
Change massif, exp-bbv and cachegrind to use this functionality.

This patch changes the interface and behaviour of VG_(demangle) and
VG_(maybe_Z_demangle). Instead of copying the demangled name into a
fixed sized buffer that is passed in from the caller (HChar *buf, Int n_buf),
the demangling functions will now return a pointer to the full-length
demangled name (HChar **result). It is the caller's responsiblilty to
make a copy if needed.
This change in function parameters ripples upward
- first: to get_sym_name
- then to the convenience wrappers
- VG_(get_fnname)
- VG_(get_fnname_w_offset)
- VG_(get_fnname_if_entry)
- VG_(get_fnname_raw)
- VG_(get_fnname_no_cxx_demangle)
- VG_(get_datasym_and_offset)
The changes in foComplete then forces the arguments of
- VG_(get_objname) to be changed as well
There are some issues regarding the ownership and persistence of
character strings to consider.
In general, the returned character string is owned by "somebody else"
which means the caller must not free it. Also, the caller must not
modify the returned string as it possibly points to read only memory.
Additionally, the returned string is not necessarily persistent. Here are
the scenarios:
- the returned string is a demangled function name in which case the
memory holding the string will be freed when the demangler is called again.
- the returned string hangs off of a DebugInfo structure in which case
it will be freed when the DebugInfo is discarded
- the returned string hangs off of a segment in the address space manager
in which case it may be overwritten when the segment is merged with
another segment
So the rule of thunb here is: if in doubt strdup the string.

as suggested by John Reiser and Greg Parker.
It seems that GCC has a more relaxed attitude about what it accepts
as valid input.

There were some easy-to-resolve conflicts.
Then I had to fix up coregrind/link_tool_exe*.in -- those files had been
added independently on both the trunk and the branch, AFAICT. I just
overwrote the trunk versions with the branch versions.

executables. Gets rid of the linker script kludgery and uniformly
uses -Ttext=0x38000000 (or whatever) on Linux, so as to accomodate
both traditional ld and gold. Should fix#193413 although I have
been unable to test it. Using a whole new program seems like
overkill, but this is infrastructure to support static linking of
the tool executables on MacOS too.

- Actually remove the dead docs/images/massif*.png files (this was meant to
happen in r10720).
- Inline $TOOL/docs/Makefile.am into $TOOL/Makefile.am for all 10 tools. 10
fewer Makefile.am files FTW!

line options. This commit changes them to all <option>.
Also make consistent how options with multiple names (eg. -h --help) are
shown.
Also, remove section describing --help and --version in Callgrind's chapter;
these aren't necessary and are presumably a hangover from when Callgrind was
a separate tool.

- There were detailed descriptions of all the tools in the Quick Start
Guide, the Manual introduction, and the start of each tool chapter. To
avoid duplication/overlap, I removed these altogether from the Quick Start
Guide, and shortened them in the intro.
- Improved the description of what errors Memcheck can find.
- Made all tool chapters start with "Overview" section, for consistency.
- Made the "run with --tool=XXX" bit consistent in each tool chapter.
- Made all tool chapter titles match the description given when running them.
- Added BBV to the User Manual intro.
- Generally clarified, updated, and future-proofed various bits of text in
the Quick Start Guide and User Manual introduction.
Also:
- Changed Nulgrind's start-up description to "the minimal Valgrind tool".
- Fixed some punctuation in the usage message.

This causes the regression test to fail with the "million" benchmark
on a Fedora 9 system. For now, remove the pc-file part of the test,
and later I'll come up with a better way of testing this feature.
