Update documentation in struct quick_symbol_functions

Paul sent me this documentiion update when I asked him a question

gdb/ChangeLog:

        * symfile.h (struct quick_symbol_functions): Update the
        documentation for field map_matching_symbols.

wrong value returned by ada-lang.c:compare_names

The ada-lang.c:compare_names function returns the wrong value
when the first string starts with the same contents as the second
string, followed by '_' and then some characters that do not make
a symbol name suffix.  For instance:

    string1 = "generics__test_generics__instance__print"
    string2 = "generics__test_generics"

In that case, compare_names (string1, string2) return -1, when
clearly, string1 is greater than string2.

A consequence of this problem is that GDB may fail to lookup
"generics.test_generics" from our partial symtabs, because
partial symbols are ordered by strcmp_iw_ordered:

    (gdb) b generics.test_generics
    Function "generics.test_generics" not defined.
    Make breakpoint pending on future shared library load? (y or [n])

gdb/ChangeLog:

        * ada-lang.c (compare_names): Fix wrong return value in case
        string1 starts with the same contents as string2, followed
        by an underscore that do not start a symbol name suffix.

remove use of sprintf_vma in remote_get_tracepoint_status
