parser: batched read operation for speed.
As a result of this change, the startup time is reduced.
The command txr -e '(compile-toplevel nil)' shows a 54%
speedup: around 110 milliseconds down from around 170.
Programs that read large amounts of TXR Lisp data will
benefit.
* parser.l (YY_INPUT): Use new get_bytes function instead of
get_byte to read a buffer at a time.
* stream.c (get_bytes): New function.
* stream.h (get_bytes): Declared.
