- update comment re offset scaling
- ppc32 offset is in bytes, not pages
- don't deal with MAP_FIXED case directly here; instead uniformly pass
all requests to VG_(am_get_advisory), so that layout policy is controlled
from one place only.

not bytes. This is a horrible kludge of a fix and it should probably
be fixed properly with a separate sys_mmap for amd64.

requests were being granted at the requested address when they should
not have been. This was causing ppc32-linux to crash at startup
(since the wrongly-granted mapping annihilated 5 others). This shows
the value of a multiplatform approach -- the bug applies to all
targets, yet x86 and amd64 appeared to work perfectly.

- on 64-bit platforms, double the size of the supported address
space to 32G.
- Increase the size of the ExeContext table 6 times. Some very
large apps have been observed to have been doing a lot of
searching in the old 4999 entry table. This table may be
OSetified in the fullness of time.

and so is not part of a module cycle. This requires a moderately
grotty hack of passing a continuation-function pointer in a global
variable.

- Move VG_(fd_{soft,hard}_limit) into m_clientstate
- m_main: clean up auxv handling. Get rid of scan_auxv().
- m_main: move scan_colsep() to somewhere more sensible.

changes from r4341 through r4787 inclusive). That branch is now dead.
Please do not commit anything else to it.
For the most part the merge was not troublesome. The main areas of
uncertainty are:
- build system: I had to import by hand Makefile.core-AM_CPPFLAGS.am
and include it in a couple of places. Building etc seems to still
work, but I haven't tried building the documentation.
- syscall wrappers: Following analysis by Greg & Nick, a whole lot of
stuff was moved from -generic to -linux after the branch was created.
I think that is satisfactorily glued back together now.
- Regtests: although this appears to work, no .out files appear, which
is strange, and makes it hard to diagnose regtest failures. In
particular memcheck/tests/x86/scalar.stderr.exp remains in a
conflicted state.
- amd64 is broken (slightly), and ppc32 will be unbuildable. I'll
attend to the former shortly.

Also reinstated SF_DEVICE, which is used to ensure we don't try and
leakcheck a page that is mapped from a device. This got lost in the
2.x-to-3.x transition, or some time after.
