Summary: [patch] syslogd converts all 8-bit chars to M-x
sequences

patch to add locale support to syslogd when converting strings to "safe"
sequences
syslogd has code to convert all logged messages to "safe" strings.
At the moment, the code converts control characters to "^x" sequences and ALL
8-bit characters to "M-x" sequences. This means that printable characters in
character sets other than ASCII are converted and so do not display as expected
when viewing the logs.
This patch adds LC_CTYPE locale support to syslogd and changes the "safe"
conversion code to examine the logged characters using mbrtoc32() and to use
iswgraph() to test if a character needs converting to safe sequences.
It also uses vis() to do the conversion which is similar to OpenBSD but which
means control chars become \C-x and non-graphical 8-bit chars become \M-x.
