Subject: Refactor charset plugins a bit and add CP437 module. Now all 8-bit
 charsets with gaps (not all symbols defined) could be produced through one
 macro -- SMB_GENERATE_CHARSET_MODULE_8_BIT_GAP(CHARSETNAME) within source
 file with three charset tables. Full source code for such modules can be
 generated by source/script/gen-8bit-gap.sh script which was taken from GNU
 libc and changed slightly to follow our data types and structure. (This used
 to be commit 37042c7bc0f349370e93e4bed37d8fa371013247)
