[PATCH v2 2/3] gdb: Rename fputs_unfiltered to ui_file_puts.

[Iain Buclaw <ibuclaw@gdcproject.org>]

[-- Attachment #1: Type: text/plain, Size: 994 bytes --]

This patch redefines fputs_unfiltered in utils.c, with new behavior to forward parameters to fputs_maybe_filtered.  This makes fputs_unfiltered identical to fputs_filtered, except filtering is disabled.

Some callers of fputs_unfiltered have been updated to use ui_file_puts where they were using other ui_file_* functions anyway for IO.

This fixes the problem I saw with \032\032post-prompt annotation being flushed to stdout in the wrong order.
