Simon Marchi e6a58aa8a7 Add xml_escape_text_append and use it
[This patch should go on top of "linux_qxfer_libraries_svr4: Use
 std::string", I should have sent them together as a series.]

I noticed that linux_qxfer_libraries_svr4 used xml_escape_text, which
returns an std::string.  That string is then copied into a larger
buffer.  It would be more efficient if we had a version of
xml_escape_text which appended to an existing string instead of
returning a new one.  This is what this patch does.

I manually verified that the output of linux_qxfer_libraries_svr4 didn't
change before/after the patch.

gdb/ChangeLog:

	* common/xml-utils.c (xml_escape_text): Move code to...
	(xml_escape_text_append): ... this new function.
	* common/xml-utils.h (xml_escape_text_append): New declaration.
	* unittests/xml-utils-selftests.c (test_xml_escape_text_append):
	New function.
	(_initialize_xml_utils): register test_xml_escape_text_append as
	a selftest.

gdb/gdbserver/ChangeLog:

	* linux-low.c (linux_qxfer_libraries_svr4): Use
	xml_escape_text_append.
