Having the builtin terminfo DB as a table, with one entry per
capability/value pair was ineffective memory-wise - we ended up adding
~20K to the final binary size.
This patch changes the internal representation from a table, to a
single NULL-separated (and NULL-terminated) char array:
cap1-name \0 cap1-value \0 cap2-name \0 cap2-value \0
The capabilities are still sorted; to lookup a capability we need to
scan from the beginning until we either find a match, or until the
capabilities from the DB sort higher (lexicographically) than the
searched-for capability.
The terminfo char array is 3.3K - more better than before.
This script parses a terminfo source file and generates a C header
file with a static struct containing terminfo names and their values.
The table is sorted on the capability names
