Optimize `peek-char'.
This makes `peek-char' 40x faster on a port whose encoding is
faster on a UTF-8 port containing multi-byte codepoints.
The `xml->sxml' procedure is 4x faster on a 2.7 MiB XML file.
* libguile/ports.c (get_codepoint): New procedure, moved here from
`scm_getc', with the additional BUF and LEN parameters.
(scm_getc): Use it.
(scm_peek_char): Use it instead of the `scm_getc'/`scm_ungetc'
sequence.
* test-suite/tests/ports.test ("string ports")["peek-char [latin-1]",
"peek-char [utf-8]"]: New tests.
* benchmark-suite/Makefile.am (SCM_BENCHMARKS): Add
`benchmarks/ports.bm'.
* benchmark-suite/benchmarks/ports.bm: New file.
