Use strnlen() instead of strlen() on the algorithm and coefficient name
string arrays in V1 wmfw files.
In V1 wmfw files the name is a NUL-terminated string in a fixed-size
array. cs_dsp should protect against overrunning the array if the NUL
terminator is missing.

Don't take this. It applies to 6.11 but not to 6.10.
I'll try to sort out one that applies to new and old code, or
send separate 6.11 and backport versions.
Sorry about that.
