gdbtypes.resolve_dynamic_range: Add function description.

gdb/ChangeLog:

        * gdbtypes (resolve_dynamic_range): Add function description.
thinko in serial.c::serial_write debug trace

I noticed that, when using 'set debug serial 1', the "write" traces
would always be NUL characters:

    [
    w \x00][\x00][\x00][\x00][\x00][etc]

This is due to a small thinko in the loop that output each character,
where we accidently used the loop boundary instead of the loop index
to index the character to be printed.

After this patch is applied, the output now becomes:

    [
    w $][v][C][o][n][t][?][#][4][9]

gdb/ChangeLog:

	* serial.c (serial_write): Fix index of character to be printed
	in call to serial_logchar when serial debug traces are enabled.
Unwrap symbols for debug information

Fixes issues with dwz multi-file (-m) and ld's -wrap option.
Symbols referenced from DWARF debug info in a separate file, eg. to
specify low and high pc, must use the real symbol.  The DWARF info
is specifying attributes of the real function, not one interposed
with --wrap.

Wrap PyObject_Get/HasAttrString in a function with second arg having const qualifier.

This is done to avoid errors when compiled with -Werror against Python-2.4
which did not have the const qualifier for the second argument of these
functions.

	* python/python-internal.h (gdb_PyObject_GetAttrString)
	(gdb_PyObject_HasAttrString): New inline function definitions.
	* py-value.c (get_field_flag): Remove the now unnecessary cast to
	char * of the second argument to PyObject_GetAttrString.
