Julian Seward 287d92271f The m_syswrap subsystem is Valgrind's model of how the kernel behaves ...

with respect to syscalls.  It is detailed and comprehensive but does
not offer a way to deal with minor deviations in behaviour from the
vanilla kernel sources, either due to running a hacked kernel or
running a vanilla kernel with a custom kernel module loaded.

This commit adds a flexible way to handle such cases without polluting
the vanilla handler syswrap-*.c files or their supporting vki_*.h
header files.  For each OS, a syswrap-OS-variants.c file is added,
containing wrappers for variants of OS.  A new command line flag
--kernel-variants= carries a comma separated list of variant names
that apply to the current run.  There are no other changes.
