Windows-specific iterate_over_objfiles_in_search_order

This patch sets the windows target to use their own version of
the iterate_over_objfiles_in_search_order gdbarch method, in
order to make global symbol searches sensitive to the current
objfile.

gdb/ChangeLog:

        * windows-tdep.h (windows_iterate_over_objfiles_in_search_order):
        Add declaration.
        * windows-tdep.c: #include "objfiles.h".
        (windows_iterate_over_objfiles_in_search_order): New function.
        * amd64-windows-tdep.c (amd64_windows_init_abi): Set
        iterate_over_objfiles_in_search_order gdbarch method to
        windows_iterate_over_objfiles_in_search_order.
        * i386-cygwin-tdep.c (i386_cygwin_init_abi): Likewise.

New "iterate_over_objfiles_in_search_order" gdbarch method.

This patch introduces the "iterate_over_objfiles_in_search_order"
gdbarch method, as well as its default implementation, and converts
the areas where it will matter to using this gdbarch method.

The default method implementation is the only one installed, and
the changes should have no functional impact in terms of behavior.
This only paves the way for the architectures that will need their
own version.

gdb/ChangeLog:

        * gdbarch.sh: Add generation of
        "iterate_over_objfiles_in_search_order_cb_ftype" typedef in
        gdbarch.h.  Add include of "objfiles.h" in gdbarch.c.
        (iterate_over_objfiles_in_search_order): New gdbarch method.
        * gdbarch.h, gdbarch.c: Regenerate.
        * objfiles.h (default_iterate_over_objfiles_in_search_order):
        Add declaration.
        * objfiles.c (default_iterate_over_objfiles_in_search_order):
        New function.
        * symtab.c (lookup_symbol_aux_objfile): New function, extracted
        out of lookup_symbol_aux_symtabs.
        (lookup_symbol_aux_symtabs): Replace extracted-out code by
        call to lookup_symbol_aux_objfile.
        (struct global_sym_lookup_data): New type.
        (lookup_symbol_global_iterator_cb): New function.
        (lookup_symbol_global): Search for symbol using
        gdbarch_iterate_over_objfiles_in_search_order and
        lookup_symbol_global_iterator_cb.
        * findvar.c (struct minsym_lookup_data): New type.
        (minsym_lookup_iterator_cb): New function.
        (default_read_var_value) [case LOC_UNRESOLVED]: Resolve the
        symbol's address via gdbarch_iterate_over_objfiles_in_search_order
        and minsym_lookup_iterator_cb.

Revert "Search global symbols from the expression's block objfile first."

The search order used in this patch breaks global symbol lookups
for certain symbols when copy-relocation is used.  A slightly different
search order will be implemented later.

gdb/ChangeLog:

        Revert the following patch:
        * findvar.c (default_read_var_value): For LOC_UNRESOLVED symbols,
        try locating the symbol in the symbol's own objfile first, before
        extending the search to all objfiles.
        * symtab.c (lookup_symbol_aux_objfile): New function, extracted
        out of lookup_symbol_aux_symtabs.
        (lookup_symbol_aux_symtabs): Add new parameter "exclude_objfile".
        Replace extracted-out code by call to lookup_symbol_aux_objfile.
        Do not search EXCLUDE_OBJFILE.
        (lookup_static_symbol_aux): Update call to lookup_symbol_aux_symtabs.
        (lookup_symbol_global): Search for matches in the block's objfile
        first, before searching all other objfiles.

Make ctxobj.exp and print-file-var.exp work on all platforms.

This patch adjusts the testing strategy used in a couple of testcases
where we are trying to print the value of a global variable defined
at multiple locations.  The problem is that the actual value depends
on the platform.  So instead of hard-coding the expected value in
the testcase script, we use local variables (in the inferior) holding
the correct value, and we compare the global variable's value with
the local variable's value.

gdb/testsuite/ChangeLog:

        * gdb.base/ctxobj-f.c (GET_VERSION): Introduce local variable
        and add comment.
        * gdb.base/ctxobj-m.c (main): Rewrite, and add comment.
        * gdb.base/ctxobj.exp: Insert breakpoint in ctxobj-f.c using
        "STOP" marker.  Adjust testing strategy to make it work on
        all targets.

        * gdb.base/print-file-var-main.c (main): Rewrite using local
        variables and adjust get_version_2's return value check.
        Add small comment.
        * gdb.base/print-file-var.exp: Insert breakpoint using "STOP"
        marker.  Adjust testing strategy to make it work on all targets.

stop parsing breakpoint command if invalid keyword found

With an Ada program, trying to break on a specific Ada task, but
with the wrong capitalization of the `task' keyword, we currently
get only pieces of the "garbage" that caused the error:

    (gdb) b *rendez_vous'address TASK 2
    Garbage 2 at end of command

Pushing this a little further:

    (gdb) b *rendez_vous'address TASK Task TaSK 2
    Garbage 2 at end of command

Another interesting failure mode:

    (gdb) b *rendez_vous'address TASK if
    Argument required (expression to compute).

The parser skipped `TASK', then found the `if' keyword, and thus
started looking for a condition.

This patch fixes the problem by aborting the parsing as soon as
an invalid keyword is found.  This makes it consistent with the
case where the REST parameter is passed as NULL (where an error
is raised immediately after seeing the first invalid keyword).

It also introduces a new testcase that reproduces all above scenarios.

gdb/ChangeLog:

        * breakpoint.c (find_condition_and_thread): Stop parsing
        as soon as the first invalid keyword is found.

gdb/testsuite/ChangeLog:

        * gdb.ada/bad-task-bp-keyword: New testcase.

copyright.py: Add gdb/CONTRIBUTE to EXCLUDE_LIST.

Normally, all files should have a copyright header, but gdb/CONTRIBUTE
currently doesn't, and it adding one at the top of the file would
probably be more pollution than information.  So don't require
a copyright header for now.

gdb/ChangeLog:

        * copyright.py (EXCLUDE_LIST): Add 'gdb/CONTRIBUTE' to list.

Add copyright header to config/djgpp/djcheck.sh.

gdb/ChangeLog:

        * config/djgpp/djcheck.sh: Add copyright header.

stubs/ia64vms-stub.c: Fix copyright header.

There is an extra coma after the copyright year which tricks
gnulib's update-copyright script.

gdb/stubs/ChangeLog:

        * ia64vms-stub.c: Adjust copyright header to follow convention
        expected by gnulib's update-copyright script.

copyright.py: Update path to gnulib import.

The location where we store the gnulib import has changed.
This patch updates accordingly the path to gnulib's update-copyright
script.

gdb/ChangeLog:

        * copyright.py (update_files, main): Fix path to update-copyright
        script.
