causes child processes after fork to fall completely silent, which can
make the output a lot less confusing. In addition it is pretty much
essential in XML output mode, so as to avoid mixing up any child XML
output with the parent's.

suggested in #119404.
Prior to this commit, if the current traced process attempted to
execve a setuid executable, an error was always returned. The revised
behaviour is:
If the current (traced) process attempts to execve a setuid
executable:
* If --trace-children=yes is not in effect, the execve is allowed.
* If --trace-children=yes is in effect, the execve is disallowed
(as at present), but an error message is printed (unless in XML mode),
so at least the execve does not fail silently any more.
As per discussion on #119404 we could probably do a lot better, but
these changes are at least simple, useful and uncontroversial.

says (essentially) "I am the replacement for function foo in object w/
soname bar.so". Now, if a redirection is mandatory, and bar.so is
loaded but foo is not found in its symbol table, then V aborts.
The initial motivation for this is making Memcheck work sanely on
glibc-2.6.X ppc32-linux. We really need to intercept 'strlen' in
ld.so right from startup. If ld.so does not have a visible 'strlen'
symbol, Memcheck generates an impossible number of errors resulting
from highly tuned strlen implementation in ld.so, and is completely
unusable -- the resulting undefinedness eventually seeps everywhere.

In dump.c, gcc complains that 'param max-stack-frame-growth' would be
exceeded, so remove 'inline' spec.
All other warnings are of the form 'call is unlikely and code size
would grow'. These aren't interesting. Remove -Winline.

- Add a VG_DBL_CLO for fractional arguments.
- Make Massif's --threshold and --peak-inaccuracy arguments fractional.

the string converted wasn't entirely numeric. Using them for numeric
command-line options -- previously if you had a option "--foo=<n>", where
<n> is supposed to be an integer, then "--foo=blah" would be interpreted as
"--foo=0", because the "blah" would be converted to zero and the remaining
chars wouldn't be noticed.
Fixed an incorrect command-line option in two massif tests that this change
exposed.

aliasing rules by casting through (char*) as an intermediate type,
rather than through (void*). This seems at least moderately
justifiable since the ANSI C standard explicitly says that any object
may be accessed through a char pointer.

tarball fails. As it stands omega.h is not installed into
$prefix/include/valgrind, so cannot be used in client requests.
Perhaps it should be.

sizes up to a multiple of 8 (or whatever --alignment is). This is combined
with the "admin" bytes, resulting in the "extra" bytes. Added
VG_(malloc_usable_size) to the tool interface to support this.

Allow a test to have any number of .stderr.exp* files, so long as at
least one is found. In fact the comments in the code that claimed
that .stderr.exp[0-9] are the only ones allowed were misleading;
.stderr.exp* has always been allowed. The only functional change here
is to mandate that at least one such file exists; prior to the change
the script mandated that at least a .stderr.exp (with no other suffix)
file existed.
Purpose is to allow collections of .stderr.exp files with suffixes
arranged in some meaningful way, eg, foo.stderr.exp-glibc25-amd64.
This might help in making testsuites more maintainable when there
have to be multiple .stderr.exp files. Naming them merely as
.stderr.exp1, .stderr.exp2, etc, makes it impossible to remember
what the differences between the files actually is.
