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.

8a5d352733 Portability: fix "EOFException: premature end of file" doing ELF on Windows. 
OutputFile::read() was bad news; fsync() should work, but was missing.

e6357b81eb NetBSD version 5 requires PT_NOTE for PaX. Also adjust other *BSD and PT_NOTE. 
[Tested OK on FreeBSD 8.1, NetBSD 5.1, OpenBSD 4.8.  Cleanup needed.]

d2718e99a4 Change class PackLinuxI386elf : public PackLinuxI386 
into   class PackLinuxElf32x86 : public PackLinuxElf32Le : public PackLinuxElf32
which makes the code for compressing ELF (for direct-to-memory decompression)
cleaner because ELF has some of the class tree to itself.
This assumes PROT_EXEC|PROT_WRITE ought to work.
This is checked at runtime, and if it fails then
give a message on stderr and exit(127).

Modify --force-execve so that runtime avoids PROT_EXEC|PROT_WRITE.
Then executables compressed with --force-execve will run under
PaX, grSecurity, and strict SELinux.
