Subject: [PATCH] * mipsread.c (read_mips_symtab, read_the_mips_symtab):  Use
 real filename with error messages. * stack.c (frame_select_command):  Rename
 to select_frame_command to avoid "fr" and "fra" having nonunique completions.
 * symfile.c (sort_symtab_syms):  Ignore sort of zero symtab *.
 (symfile_init):  Print file format name when unable to handle it.
 (free_named_symtabs):  Use BLOCKVECTOR rather than obsolete BLOCKLIST. *
 symmisc.c (free_symtab):  Only free linetable if nonzero. * symtab.h:  Remove
 obsolete BLOCKLIST macros.
