Add new APIs that take 64-bit length parameters: sqlite3_malloc64(),

Browse Source 
sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_text64(),
sqlite3_result_blob64(), and sqlite3_result_text64().
Add the sqlite3_msize() interface.
Internal memory allocation routines now use 64-bit unsigned
length parameters for safety.
Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid
a integer overflow problem.
