Remove several trivially-unnecessary uses of nested functions.

Browse source 
* grub-core/commands/i386/pc/sendkey.c
(grub_cmd_sendkey: find_key_code, find_ascii_code): Make static
instead of nested.
* grub-core/commands/legacycfg.c (legacy_file: getline): Likewise.
Rename to ...
(legacy_file_getline): ... this.

Likewise.

(grub_linuxbios_table_iterate: check_signature): Likewise.
* grub-core/kern/parser.c (grub_parser_split_cmdline:

* grub-core/lib/arg.c (find_short: fnd_short): Likewise.  Pass
an additional parameter.
