Fix a typo in the documentation. Fix the new sqlite3_result_text64() routine
so that it works correctly with an encoding parameter of SQLITE_UTF16.

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.

memcpy() to move the value back into its register
after the function returns. This runs faster and saves over 500 bytes
of code space.
