-Wextra enables a bunch of rather useful checks which this fixes.
This changes the return value for the case when no ELF headers were found
to avoid (ugly-ish) cast of -1 to unsigned.

Changes:
v2:
* cast the return value to (int)
* added missing (long)
Implement elf_get_file_size to determine the size of an ELF image
that has been loaded into a buffer much larger than the actual size
of the original file. We determine the size by searching for the
farthest offset declared by the ELF headers.

Trampoline code in the LE binary were helping fix this. This patch now
takes care of switching the mode to LE for LE elf binaries.

v2: With the parameters changed for go-64, kernel loading from commandline broke
v3: (client-exec) calls start-elf64 directly, fix args
We byte swap the entire header in place in elf_check_file.

It's cumbersome to maintain code twice, in Forth and in C, and now that libelf
has a new important feature (relocation), I removed most of the old Forth
functions for ELF loading and use the libelf everywhere instead.

Split elf.c into elf32.c and elf64.c for better readability. Added relocation
code to libelf for 64-bit ELF images, modified the Paflof Makefile to link
the executable with relocation information and load Paflof now to the upper
end of the memory.
