[PATCH 3/3] Remove usage of VEC(char_ptr) in gdbscm_parse_function_args

[Simon Marchi <simon.marchi@ericsson.com>]

From: Simon Marchi <simon.marchi@polymtl.ca>

This is a straightforward replacement, no change in behavior are
intended/expected.

This is the last usage of VEC(char_ptr), so it can now be removed.

gdb/ChangeLog:

	* guile/scm-utils.c (gdbscm_parse_function_args): Replace VEC
	with std::vector.
	* common/gdb_vecs.h (DEF_VEC_P (char_ptr)): Remove.
