PC-relative relocations (jumps and calls).
- Allow SEG:OFF to be used as just an offset portion (like NASM does).
- Labels in absolute sections that are declared global are given the correct
absolute value in the symbol table.
One difference from NASM:
label equ 0040h:001eh
jmp label
in NASM means the same as:
jmp 001eh (a near jump)
but yasm will treat this the same as:
jmp 0040h:001eh (a far jump)
I'm still not completely happy with this implementation, but it's workable
and fixes all the bugs I've found so far in absolute handling.

sections. This breaks section numbering between the file section headers
and the section numbering used by symbols to reference sections.
While we're here, don't even try to number sections during parse... this
numbering is getting overwritten anyway.
Fixes#59 (reported by hkmaly@gmail.com).

object formats without creating duplicate lists of symbols. XDF and COFF
were updated; ELF needs to reorder the symbols on its own, so for now it's
not been updated to use the common implementation.
* hamt.c (HAMTEntry, HAMT, HAMT_destroy)
(HAMT_insert): Change SLIST to STAILQ.
* symrec.c (sym_type): Add SYM_SPECIAL.
(yasm_symtab_define_special): New.
(yasm_symrec_declare): New; includes all functionality from symtab_declare.
(yasm_symtab_declare): Call yasm_symrec_declare now.
(yasm_symrec_is_special): New.
* symrec.h: Add prototypes for above.
* xdf-objfmt.c: Use symrec_data instead of declaring xdf_symtab.
* xdflong.hex, xdfprotect.hex, xdfother.hex: Update due to symbol reordering.
* coff-objfmt.c: Use symrec_data instead of declaring coff_symtab.
* elftimes.hex, elfso.hex, elfabssect.hex: Update due to symbol reordering.
* elfglobext.hex, elf-x86id.hex, elftest.hex, elfso64.hex: Likewise.
* stabs-elf.hex: Likewise.

preventing a segfault. The assumptions it had made for all sections
were wrong with absolute sections, so added just as much special casing
as necessary. I hope the output is correct as well - this way we should
at least get bugs if it's wrong.

another test such that linked together they verify that
1. It links properly
2. The constant is loaded properly
3. The function is called properly
shown (probably not proved) by the program exiting with error level 0.

To ensure all section start addresses are known, added a first pre-pass of
sections to calculate each one's address.
