  [lldb] [llgs server] Support creating core dumps on NetBSD

Add a new SaveCore() process method that can be used to request a core
dump.  This is currently implemented on NetBSD via the PT_DUMPCORE
ptrace(2) request, and enabled via 'savecore' extension.

Protocol-wise, a new qSaveCore packet is introduced.  It accepts zero
or more semicolon-separated key:value options, invokes the core dump
and returns a key:value response.  Currently the only option supported
is "path-hint", and the return value contains the "path" actually used.
The support for the feature is exposed via qSaveCore qSupported feature.
