+/*************************************************************************
+ * <ghdlserver.c> FOSSEE, IIT-Mumbai
+ * 24.Mar.2017 - Raj Mohan - Added signal handler for SIGUSR1, to handle an
+ * orphan test bench process.
+ * The test bench will now create a PID file in
+ * /tmp directory with the name
+ * NGHDL_<ngspice pid>_<test bench>_<instance_id>
+ * This file contains the PID of the test bench .
+ * On exit, the test bench removes this file.
+ * The SIGUSR1 signal serves the same purpose as the
+ * "End" signal.
+ * - Added syslog interface for logging.
+ * - Enabled SO_REUSEADDR socket option.
+ * - Added the following functions:
+ * o create_pid_file()
+ * o get_ngspice_pid()
+ * 22.Feb.2017 - Raj Mohan - Implemented a kludge to fix a problem in the
+ * test bench VHDL code.
+ * - Changed sleep() to nanosleep().
+ * 10.Feb.2017 - Raj Mohan - Log messages with timestamp/code clean up.
+ * Added the following functions:
+ * o curtim()
+ * o print_hash_table()

+ * (the extent to which this is true is a measure of the quality of
+ * the hash function as it applies to the key domain).
+ *
+ * With the items distributed into more buckets, the chain length
+ * (item count) in each bucket is reduced. Thus by expanding buckets
+ * the hash keeps a bound on the chain length. This bounded chain
+ * length is the essence of how a hash provides constant time lookup.
+ *
+ * The calculation of tbl->ideal_chain_maxlen below deserves some
+ * explanation. First, keep in mind that we're calculating the ideal
+ * maximum chain length based on the *new* (doubled) bucket count.
+ * In fractions this is just n/b (n=number of items,b=new num buckets).
+ * Since the ideal chain length is an integer, we want to calculate
+ * ceil(n/b). We don't depend on floating point arithmetic in this
+ * hash, so to calculate ceil(n/b) with integers we could write
+ *
+ * ceil(n/b) = (n/b) + ((n%b)?1:0)
+ *
+ * and in fact a previous version of this hash did just that.
+ * But now we have improved things a bit by recognizing that b is
+ * always a power of two. We keep its base 2 log handy (call it lb),
+ * so now we can write this with a bit shift and logical AND:
+ *
+ * ceil(n/b) = (n>>lb) + ( (n & (b-1)) ? 1:0)
