Jason Molenda 2b8b783b1a Quote error string from qLaunchSuccess ...

If the error message from qLaunchSucess included a gdb RSP
metacharacter, it could crash lldb.  Apply the binary
escaping to the string before sending it to lldb; lldb
promiscuously applies the binary escaping protocol on
packets it receives.

Also fix a small bug in cstring_to_asciihex_string where
a high bit character (eg utf-8 chars) would not be
quoted correctly due to signed char fun.
