uCON64 Code (SVN)

- Cast is necessary on 64-bit Cygwin.

- Updated quick_io*() functions to support large file I/O, including on capable
32-bit systems.
- Updated --poke to support a 64-bit offset.
- Modified --hfind and --hfindr to accept search strings without spaces.

- Fixed quick_io_func() to return the correct number of processed bytes in all
three cases for ending the loop. The return value is not used in uCON64.

- Removed redundant/incorrect assignments to errno.
- Fixed signed/unsigned mismatch.

- Addressed some inconsistencies and needless limitations in the quick_io*()
functions.
+ Updated all client code.

- Added support for up to 64 Mbit LoROM games to --gd3. It works at least for
the 48 Mbit English fan translation of Fire Emblem - Thraki 776 (J) (V.ROM)
(Lil' Manster 1.07).

- Fixed warning when compiling with Visual C++ 2015.

- Made --gd3 write correct SRAM mapping values for Trials of Mana.
- Added support for 64 Mbit HiROM games to --gd3. It works at least for the
English fan translation of Fire Emblem 4: Genealogy of the Holy War ("Project
Naga", beta version 7).

- Fixed issue with -crc on large files (>2GB).

- Fixed issue when compiling with MinGW-w64 with -D_FILE_OFFSET_BITS=64.
