psymtab cleanup patch 1/3

This is the first of a set of three patches to cleanup psymtab.c a bit.

Basically, these two functions do not belong in psymtab.c:
expand_partial_symbol_names, map_partial_symbol_filenames,
and "partial" does not belong in the function name.

This first patch moves them to a better location.
The second patch adds some typedefs for function parameters to
quick_symbol_functions.expand_symtabs_matching.
The third patch removes "partial" from the function names
and uses them in more places.

	* psymtab.c (expand_partial_symbol_names): Delete, moved to symfile.c.
	(map_partial_symbol_filenames): Ditto.
	* psymtab.h (expand_partial_symbol_names): Delete, moved to symfile.h.
	(map_partial_symbol_filenames): Ditto.
	* symfile.c (expand_partial_symbol_names): Moved here from psymtab.c.
	(map_partial_symbol_filenames): Ditto.
	* symfile.h (expand_partial_symbol_names): Moved here from psymtab.h.
	(map_partial_symbol_filenames): Ditto.
	* symtab.c: Delete #include "psymtab.h".
psymtab cleanup patch 2/3

This patch adds two typedefs:
expand_symtabs_file_matcher_ftype
expand_symtabs_symbol_matcher_ftype

It also renames the NAME_MATCHER argument in expand_symtabs_matching.
The function is named expand_symtabs_matching and it takes a name_matcher
argument.  Name of what?  The symtab?  A symbol?
I made it SYMBOL_MATCHER to make it clearer.

	* symfile.h (expand_symtabs_file_matcher_ftype): New typedef.
	(expand_symtabs_symbol_matcher_ftype): New typedef.
	(quick_symbol_functions.expand_symtabs_matching): Update to use.
	expand_symtabs_file_matcher_ftype, expand_symtabs_symbol_matcher_ftype.
	* symfile.c (expand_partial_symbol_names): Update to use
	expand_symtabs_symbol_matcher_ftype.
	* dwarf2read.c (dw2_expand_symtabs_matching): Update to use
	expand_symtabs_file_matcher_ftype, expand_symtabs_symbol_matcher_ftype.
	Arg name_matcher renamed to symbol_matcher.
	* psymtab.c (recursively_search_psymtabs): Update to use
	expand_symtabs_symbol_matcher_ftype.  Arg name_matcher renamed to
	sym_matcher.
	(expand_symtabs_matching_via_partial): Update to use
	expand_symtabs_file_matcher_ftype, expand_symtabs_symbol_matcher_ftype.
	Arg name_matcher renamed to symbol_matcher.
psymtab cleanup patch 3/3

This last patch removes "partial" from the names of
expand_partial_symbol_names and map_partial_symbol_filenames.
It also renames expand_partial_symbol_names to match the
struct quick_symbol_functions "method" that it wraps:
expand_symtabs_matching.

This patch also adds two parameters to expand_symtabs_matching
so that it can fully wrap the underlying quick_symbol_functions method.
This makes it usable in more places.
I thought of having a cover function that still had the same
signature as the old expand_partial_symbol_names function,
but I couldn't think of a good name, and it wasn't clear it was
worth it anyway.

	* symfile.h (expand_symtabs_matching): Renamed from
	expand_partial_symbol_names.  Update prototype.
	(map_symbol_filenames): Renamed from map_partial_symbol_filenames.
	* symfile.c (expand_symtabs_matching): Renamed from
	expand_partial_symbol_names.  New args file_matcher, kind.
	Rename arg fun to symbol_matcher.
	(map_symbol_filenames): Renamed from map_partial_symbol_filenames.
	* ada-lang.c (ada_complete_symbol_matcher): Renamed from
	ada_expand_partial_symbol_name.
	(ada_make_symbol_completion_list): Update to call
	expand_symtabs_matching.
	(ada_add_global_exceptions): Call expand_symtabs_matching.
	* mi/mi-cmd-file.c (mi_cmd_file_list_exec_source_files): Update to
	call map_symbol_filenames.
	* symtab.c (sources_info): Update to call map_symbol_filenames.
	(search_symbols): Call expand_symtabs_matching.
	(symbol_completion_matcher): Renamed from expand_partial_symbol_name.
	(default_make_symbol_completion_list_break_on): Update to call
	expand_symtabs_matching.
	(make_source_files_completion_list): Update to call
	map_symbol_filenames.
non-PIC references to __ehdr_start in pie and shared

Rather than hacking every backend to not discard dynamic relocations
against an undefined hidden __ehdr_start, make it appear to be defined
early.  We want __ehdr_start hidden before size_dynamic_sections so
that it isn't put in .dynsym, but we do need the dynamic relocations
for a PIE or shared library with a non-PIC reference.  Defining it
early is wrong if we don't actually define the symbol later to its
proper value.  (In some cases we want to leave the symbol undefined,
for example, when the ELF header isn't loaded, and we don't have this
infomation available in before_allocation.)

Small fixes to the GDB/MI Output Syntax grammar.

This patch fixes the grammar, and tries to do it in a way that makes
the logic behind the current implementation a little clearer.

gdb/doc/ChangeLog:

        (from Yuanhui Zhang  <asmwarrior@gmail.com>)
        (from Joel Brobecker  <brobecker@adacore.com>)
        * gdb.texinfo (GDB/MI Output Syntax): Add some missing "nl"
        markers.  Remove one that was misplaced.
Add missing empty line after declarations in "if" block (py-type.c).

This patch fixes a small coding-style violation...

gdb/ChangeLog:

        * python/py-type.c (convert_field): Add missing empty line
        after declarations.
Fix small style violation in py-value.c:get_field_type

gdb/ChangeLog:

        * python/py-value.c (get_field_type): Remove unnecessary curly
        braces for single-statement if block.

Tested on x86_64-linux.
introduce async_callback_ftype

This introduces async_callback_ftype.  This is needed for
make-target-delegates to work properly, as it doesn't implement a real
parser.  I think it's also an ok cleanup in its own right.

2014-01-15  Tom Tromey  <tromey@redhat.com>

	* target.h (async_callback_ftype): New typedef.
	(struct target_ops) <to_async>: Use it.
Silence uninitialized warning on ehdr_start_save

Older GCC, like 4.1/4.2, will issue an uninitialized warning on
ehdr_start_save.  This patch silences by using

struct bfd_link_hash_entry ehdr_start_save = ehdr_start_save;

	* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation):
	Silence uninitialized warning on ehdr_start_save with older
	GCC.
Fix go32-nat.c build fallout from to_detach constification.

The recent constification of to_detach missed updating the forward
declaration of go32_detach, breaking the build:

 ../../src/gdb/go32-nat.c:387:1: error: conflicting types for 'go32_detach'
 ../../src/gdb/go32-nat.c:240:13: note: previous declaration of 'go32_detach' was here

go32_detach is actually defined before it's ever used, making the
forward declaration is unnecessary.  So we can just remove it instead
of updating it.  While at it, remove all others in the same situation.
Tested by building a djgpp gdb.
