[PATCH] acpi: acpica: utstring.c: Remove some unused functions

[Rickard Strandqvist]

Removes some functions that are not used anywhere:
acpi_ut_strlwr() acpi_ut_safe_strncat() acpi_ut_safe_strcat()
acpi_ut_safe_strcpy() ut_convert_backslashes() acpi_ut_stricmp()

This was partially found by using a static code analysis program called cppcheck.
