ed0665407a More: prefer movzbl over movb fetch to register 
Avoids hardware failure of writing 0x00 instead of the fetched byte.
1 cycle faster, 1 byte larger (but often recouped later when OR of 32-bits).
Avoid changing win*pe.S for now.

92c925fe95 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.

9e8de4abe5 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.
