d5321da8d2 Micro optimization and improved similarity with gas' output:
When two section names share a suffix, reuse the entry in shstrtab.

0da9f13faa An MCDisassembler has the option to not implement
getEDInfo(), in which case this code would dereference
NULL. EDInst can already handle NULL info, so avoid
the dereference and pass NULL through.

93f7936435 Again adding a C API to the disassembler for use by such tools as Darwin's
otool(1), this time with the needed fix for case sensitive file systems :) .
This is a work in progress as the interface for producing symbolic operands is
not done.  But a hacked prototype using information from the object file's
relocation entiries and replacing immediate operands with MCExpr's has been
shown to work with no changes to the instrucion printer.  These APIs will be
moved into a dynamic library at some point.
