When using gdb.lookup_static_symbol I think that GDB should find
static symbols (global symbol with static linkage) from the current
object file ahead of static symbols from other object files.
This means that if we have two source files f1.c and f2.c, and both
files contains 'static int foo;', then when we are stopped in f1.c a
call to 'gdb.lookup_static_symbol ("foo")' will find f1.c::foo, and if
we are stopped in f2.c we would find 'f2.c::foo'.
Given that gdb.lookup_static_symbol always returns a single symbol,
but there can be multiple static symbols with the same name GDB is
always making a choice about which symbols to return. I think that it
makes sense for the choice GDB makes in this case to match what a user
would get on the command line if they asked to 'print foo'.
gdb/testsuite/ChangeLog:

tests for gdb.lookup_static_symbol.
* gdb.python/py-symbol-2.c: New file.
gdb/doc/ChangeLog:
* python.texi (Symbols In Python): Extend documentation for
gdb.lookup_static_symbol.

Similar to lookup_global_symbol, except that it checks the
STATIC_SCOPE.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.
This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.
gdb/ChangeLog:
Update copyright year range in all GDB files.
Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.
New attribute 'last' for gdb.Symtab_and_line.
* NEWS (Python Scripting): Add entry about the new attribute.
* python/py-symtab.c (salpy_get_last): New function which
implements the get method for the 'last' attribute of
gdb.Symtab_and_line.
(sal_object_getset): Add entry for the 'last' attribute.
doc/
* gdb.texinfo (Symbol Tables In Python): Add description about
the new 'last' attribute of gdb.Symtab_and line.
testsuite/
* gdb.python/py-symtab.exp: Add tests to test the new attribute
'last' of gdb.Symtab_and_line.
* gdb.python/py-symbol.c: Move break point comment to enable
testing of gdb.Symtab_and_line.last.
Add two new methods global_block and static_block to gdb.Symtab
objects.
* NEWS (Python scripting): Add entry about the new methods.
* python/py-symtab.c (stpy_global_block): New function which
implements the gdb.Symtab.global_block() method.
(stpy_static_block): New function which implements the
gdb.Symtab.static_block() method.
(symtab_object_methods): Add entries for the two new methods.

gdb.Symtab.static_block().
* doc/gdb.texinfo (Symbol Tables In Python): Add documentation
about the new methods global_block and static_block on
gdb.Symtab objects.
