* elfparser.c (struct ElfParser): Add a cache of the text section.
* binparser.c (struct BinParser): Add a cache of a bin record to
get rid of malloc()/free() overhead.

Deal with address offsets. Address lookup is now:
- First convert the address to an offset into the file
- Then convert to an offset into the text segment
- Then add the load address of the text segment (found in the
debug binary)
- Then finally lookup the result in the symbol table.
* elfparser.c (elf_parser_get_text_offset): New function
* elfparser.c (elf_parser_lookup_symbol): Treat addresses as
offsets into the text segment.
* binfile.c (bin_file_new): Store the offset of the text section
of the actual binary (not the debug one)
(bin_file_lookup_symbol): Subtract text_offset before passing
address to elf parser.
* module/sysprof-module.c: Remove include of linux/config.h
