Sang Woo Kim ce775a80cf udpiiu: reject a non-finite or non-positive EPICS_CA_MAX_SEARCH_PERIOD 
epicsScanDouble accepts "inf" and "nan", so envGetDoubleConfigParam
returns success for them and the parsed value flows into getMaxPeriod's
only range gate, maxPeriod < maxSearchPeriodLowerLimit. That comparison
is false for both inf and NaN, so a non-finite period reaches
getNTimers(), whose static_cast<unsigned> of 1 + log(maxPeriod/...)/log2
is an undefined float->unsigned conversion: inf aborts the client in
malloc via a garbage nTimers allocation, and NaN drives the search-timer
wheel off a NaN period where every deadline comparison is false.

Gate the parsed value on finite() (from epicsMath.h) and positivity
alongside the parse status, and fall back to the default period. A
non-positive period is not a "low" period to be clamped up to the 60 s
lower limit; it takes the same invalid-input path as inf/NaN.

getMaxPeriod() is getNTimers()'s only caller, so this makes the
conversion finite and positive by construction.
