Dynamically composite xml in reply to GDB
GDBserver still uses pre-generated target descriptions in order to
reply to GDB's query on target description (see xml-builtin-generated.c
in GDBserver build directory). This patch teaches GDBserver to
create XML contents according to the target descriptions rather than
using pre-generated ones.
First, change target feature c files to pass the feature xml file
name to tdesc_create_feature, so that target description in GDBserver
can record them, and create XML contents from these features in
buffer, like
...
<xi:include href="$FEATURE1_XML_NAME"/>
<xi:include href="$FEATURE2_XML_NAME"/>
...
and send this buffer back to GDB.
Note that this patch reuses target_desc.xmltarget a little bit, which is
to hold the XML contents dynamically generated in tdesc_get_features_xml.
However, it is not xfree'ed in ~target_desc, because we can't tell it is
from xstrdup or a literal string. Since we don't delete target_desc,
there is no memory leak yet. After we change all target descriptions to
the new style, target_desc.xmltarget is from xstrdup, then, we can safely
xfree it in ~target_desc.
