1bafc58697 Get rid of --support-elan3=. This flag wasn't doing anything since 
the Elan3 user-space driver now works on unmodified Valgrind.

6789f6542e A commit which is almost all trivial change. 
- m_main: if --log-file-qualifier applies, do not add ".pid"
  at the end of the name

- Fix the logic which detected whether the just-devised name
  already existed.  This was broken (by me) because it could not
  distinguish the reasons for failing to open the logfile.

  Doing this required changing the return type of VG_(open)
  from Int to SysRes (to make failure reasons visible) and 
  that's the cause of most of the changes.

61448c507d We have a nice little collection of text files describing various high 
level things.  But they're all over the place.  This commits moves
them all to the new docs/internals/ directory, and gives them 
a consistent naming scheme.

individually to avoid complaints due to uninitialised padding bytes
on 64 bit platforms.

Also fixed sendmsg to check things which should be initialised (the
msghdr structure and the iov array) properly instead of doing a write
check for everything.

fcf186b9c8 Sort out the mess that is pread64/pwrite64 properly. All three platforms 
that we currently support use the same handlers in the kernel without any
platform specific wrappers.

The final argument is a 64 bit argument however, which means that it
requires two registers on x86 and ppc32 and only one on amd64. The
reason it works in the kernel is that x86 and ppc32 calling conventions
inside the kernel work out correctly and the values get joined together.

For our purposes we make x86 and ppc32 use the generic veneer with
five arguments and amd64 use a platform specific one with four...

fbf8653c8b Removed the remnants of the attempt at an ARM port, because it had 
bit-rotted badly and was clogging up the code.

I put the useful remnants in docs/porting-to-ARM in case anyone ever
wants to try porting to ARM again.
