It sounds like Matthew is open to changing the kalimba stub.  We should get rid 
of the hex-ascii strings (along with distribution_id, os_build, os_kernel) 
everywhere.  lldb-platform is not bundled/distributed in any products so we 
don't have to worry about deployed versions.

hostname is less clear-cut because there we're dealing with a user-specified 
string and that may include one of # $ } *.

Personally, I wish the whole of gdb-remote protocol required the use of the 
binary packet escape protocol which says that any of these 4 metacharacters 
that is meant to be sent in the body of a packet is prefixed with } and is 
xor'ed with 0x20.  But that's not what the protocol says so we need to do these 
things..
