added VIC20 UK keymaps provided by .mad.
With the patch, on Linux, it behaves like this: in log i see (once) Error - vice_network_send: internal error (ret:-1 buffer_length:14 errno:32 - Datenübergabe unterbrochen (broken pipe)) the emulation stays "frozen" (as if monitor is open) and i can't reopen the remote monitor nor the normal monitor
uimon_petscii_out() causes OOB reads
good catch! fixed in r46199 hopefully (other functions were also affected)
utf helper functions take strings, not chars, fixes #2247
UB in via1d1541.c
UB in snapshot.c
applied in r46198 - thanks!
