Alexandra Hájková b0861063a8 Add support for preadv2 and pwritev2 syscalls 
Support for amd64, x86 - 64 and 32 bit, arm64, ppc64, ppc64le,
s390x, mips64. This should work identically on all
arches, tested on x86 32bit and 64bit one, but enabled on all.

Refactor the code to be reusable between old/new syscalls. Resolve TODO
items in the code. Add the testcase for the preadv2/pwritev2 and also
add the (similar) testcase for the older preadv/pwritev syscalls.

Trying to test handling an uninitialized flag argument for the v2 syscalls
does not work because the flag always comes out as defined zero.
Turns out glibc does this deliberately on 64bit architectures because
the kernel does actually have a low_offset and high_offset argument, but
ignores the high_offset/assumes it is zero.

void* arg in x3
