log-handler: Add a config option for log size.

Allow a configuration option to specify a log size. The parameter takes and
interprets common size suffixes k/M/G. 1kB = 1024B, 1MB=1024kB, 1GB=1024MB.
Default unit is byte. If "B" is specified at the end it will be ignored.

Tested:
Tested that "logsize = 567kB" correctly sets up a 567KB log buffer.
Tested that invalid/overflow values will be ignored and 16KB will be used.
Tested that if log size smaller than pagesize is rounded up.
