[RFA] gdbserver/server.c: Replace 2x strlen() by a variable

[Markus Deuling <deuling@de.ibm.com>]

Hello,

this little patch adds a variable to prevent strlen() from being called two times.
Maybe it would also be a good idea to replace it by the hard-coded length, but I think
the code then will be less readable then.

Is it ok to apply ?

ChangeLog:

	* server.c (handle_general_set): New variable len instead
	of using strlen two times.
