placed some variables in context
fixed some function signatures
closed a few possible buffer overruns
sorry to the platform maintainers, I can't verify what I did for non-Win32 builds
With previous logic all spare threads were notified and performed
expensive loop on each request arrival. New logic wakes up only
one thread per request. (the same fix was performed in 2.0 SS lock manager
to avoid waking up all blocked threads on each lock request resolution).
As an (unexpected) result of this changes SS performance significantly
improved. Some artificial tests show timing improvements by
factor between 2 and 3.
Since we already have the define ISC_STATUS_LENGTH for the the length of
the status vector, we should use it! Replaced 'status[20]' with
'status[ISC_STATUS_LENGTH]'.
Replaced the different symbolic names for the maximum length of a path
(MAX_PATH, MAX_PATH_LENGTH, MAXPATHLEN) with one uniq symbol MAXPATHLEN.
