077793fa5e Update pefile.cpp 
I found a bug by participating to the Binary Golf Grand Prix 3 (https://tmpout.sh/bggp/3/) : upx text.exe segfaults when NumberOfSections in the IMAGE_FILE_HEADER is NULL, so 
if (memcmp(isection[0].name,"UPX",3) == 0) triggers a NULL pointer dereference causing a crash.
To fix it, just have to check if isection is NULL (which means NumberOfSections = 0) or not.

717150b7f3 Stupid MSVC: bad C4706: assignment within conditional expression 
-    for (unsigned j=0; (k = dt_names[j]); ++j) {
+    for (unsigned j=0; ((k = dt_names[j]), k); ++j) {

The complaint was:
    p_lx_elf.cpp(5710) : warning C4706: assignment within conditional expression
which is INCORRECT, as shown in the change which is 100% equivalent.
The assignment occurs BEFORE the conditional expression.

GNU_HASH table when there is no ElfXX_Shdr for it.  64-bit only for now.

e7ca5c54ff Fix --brute for p_lx_elf.cpp, which compresses multiple pieces 
Force all pieces to use the same de-compressor.
(Future: allow each PT_LOAD to choose its own.)
Has minor wobbles due to page alignment, and size of de-compressor.
64-bit only for now.
