- minimum autoconf 2.59 is now required and verified - due to issues with AS_HELP_STRING

- native win32 now handles WSAECONNRESET - no longer exits openocd
- qCRC packet now works correctly under cygwin (gdb compare-sections command)
- removed __USE_GNU define from gdbserver.c
- gdb qSupported packet is now handled, with this we are able to tell gdb packet size, memory map of target
- added new target script gdb_program_config - called before gdb flash programming
- new gdb server command gdb_memory_map (enable|disable> - default is disable
- new gdb server command gdb_flash_program (enable|disable> - default is disable
- gdb flash programming supported - vFlash packets
- image_elf_read_section now does not clear any remaining data, this was causing the gdb checksum to fail with certain files
- reformat of usbprog.c
- memory leak in command_print fixed
- updated texi doc to include new commands
- added gdb programming section to docs
