68f35deb86 Fixed a rare boundary problem in Packer::compressWithFilters(). 
The comparision if an update might be possible later was using
"<" instead of "<=" which resulted in missing calls to
findOverlapOverhead() and buildLoader().

Also, the comparision had not been updated for the newly added
hdr_clen fields.

This fixes sf.net bug #1477825.

268e322e1c Extra parameter for compressWithFilters and packExtent, 
to fix 2-pass problem with --brute on linux/elf386.
Only one decompression method is allowed, chosen by
smallest output for .text; but Elf headers come first.

899e7d2f39 Added internal debugging options '--fake-stub-version=X.XX' and 
'--fake-stub-year=XXXX'.

These might prove useful for building up a test suite which is able to
check binary identity of compressed executables between UPX releases
where the implementation of a specific format has not changed.
