* libguile/ports-internal.h (struct scm_port_internal): Add new members
'at_stream_start_for_bom_read' and 'at_stream_start_for_bom_write'.
(SCM_UNICODE_BOM): New macro.
(scm_i_port_iconv_descriptors): Add 'mode' parameter to prototype.
* libguile/ports.c (scm_new_port_table_entry): Initialize
'at_stream_start_for_bom_read' and 'at_stream_start_for_bom_write'.
(get_iconv_codepoint): Pass new 'mode' parameter to
'scm_i_port_iconv_descriptors'.
(get_codepoint): After reading a codepoint at stream start, record
that we're no longer at stream start, and consume a BOM where
appropriate.
(scm_seek): Set the stream start flags according to the new position.
(looking_at_bytes): New static function.
(scm_utf8_bom, scm_utf16be_bom, scm_utf16le_bom, scm_utf32be_bom,
scm_utf32le_bom): New static const arrays.
(decide_utf16_encoding, decide_utf32_encoding): New static functions.
(scm_i_port_iconv_descriptors): Add new 'mode' parameter. If the
specified encoding is UTF-16 or UTF-32, make that precise by deciding
what byte order to use, and construct iconv descriptors based on the
precise encoding.
(scm_i_set_port_encoding_x): Record that we are now at stream start.
Do not open the new iconv descriptors immediately; let them be
initialized lazily.
* libguile/print.c (display_string_using_iconv): Record that we're no
longer at stream start. Write a BOM if appropriate.
* doc/ref/api-io.texi (BOM Handling): New node.
* test-suite/tests/ports.test ("set-port-encoding!, wrong encoding"):
Adapt test to cope with the fact that 'set-port-encoding!' does not
immediately open the iconv descriptors.
(bv-read-test): New procedure.
("unicode byte-order marks (BOMs)"): New test prefix.
