Add new APIs that take 64-bit length parameters:

Browse Source 
sqlite3_malloc64(),
sqlite3_realloc64(),
sqlite3_bind_blob64(),
sqlite3_bind_texte64(),
sqlite3_result_blob64(),
and sqlite3_result_texte64().
Internal memory allocation routines also now use 64-bit unsigned length
parameters for safety.
Also add the sqlite3_msize() interface.
Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a
integer overflow problem.
