New i386/lzma-multi_d.S enables unpacking more than one block
...
Used by p_lx_exe.cpp; others keep old i386/lzma_d.S
which allows only one block, but avoids trouble with
anti-virus utilities for some OS.

i386: new stub strategy to avoid problems with early mmap layout
...
The stub occupies the same region that execve() would create
for the original progam. The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.
