Support DW_TAG_module as separate namespaces.
* dwarf2read.c (typename_concat): New parameter physname.
(read_module_type): New function and declaration.
(scan_partial_symbols): Scan also DW_TAG_module children.
(partial_die_parent_scope): Accept scope even from DW_TAG_module. Pass
to typename_concat backward compatible physname value 0.

DW_AT_MIPS_linkage_name first, extend it for language_fortran
&& physname and return there instead of just setting NAME. Extend
the main block for language_fortran. Pass physname parameter to the
typename_concat call.

missing from SYMBOL_SET_NAMES in the language_fortran case.

variables.
(read_type_die) <DW_TAG_module>: New.
(MAX_SEP_LEN): Increase to 7.
(typename_concat): New parameter physname. New variable lead. Support
also language_fortran.

* f-lang.c: Include cp-support.h.
(f_word_break_characters, f_make_symbol_completion_list): New functions.
(f_language_defn): Use cp_lookup_symbol_nonlocal,
f_word_break_characters and f_make_symbol_completion_list.

* gdbtypes.h (enum type_code) <TYPE_CODE_MODULE>: New.
* symtab.c (symbol_init_language_specific): Support language_fortran.
(symbol_find_demangled_name): New comment on language_fortran.
(symbol_natural_name, symbol_demangled_name): Use demangled_name even
for language_fortran.
(lookup_symbol_aux_local): Check imports also for language_fortran.
(default_make_symbol_completion_list): Rename to ...
(default_make_symbol_completion_list_break_on): ... this name. New
parameter break_on, use it.
(default_make_symbol_completion_list): New stub.
* symtab.h (default_make_symbol_completion_list_break_on): New
prototype.
