* cppfiles.c (safe_read): Deleted.
(read_and_prescan): New function, replaces safe_read, converts
and/or warns about trigraphs, silently converts odd line
terminators (\r, \n\r, \r\n). Warns about no newline at EOF.
(finclude): Use read_and_prescan; turn off nonblocking mode on
the input descriptor; remove file-size-examination and
no-newline-at-EOF gunk which is longer necessary; be more
careful about checking that we've been handed a legitimate
file to read (only real files, pipes, and ttys are acceptable).
* cpplib.h (cpp_options): Rename no_trigraphs flag to
`trigraphs' and invert its sense.
(trigraph_table): Declare.
(cpp_warning_with_line): Prototype.
* cpplib.c: Remove all references to trigraph_pcp. Define
trigraph_table; initialize it in initialize_char_syntax. Open
files in nonblocking mode. s/no_trigraphs/trigraphs/
throughout, and invert sense. Put cpp_warning_with_line back
in and export it.
