65640f401a Removed the requirement for isc_mem_setwater() that when the callback function 
is not null then hi_water must exceed lo_water and both must be > 0.
Now requires hi_water >= lo_water, and they can both be 0.  Not allowing
them to be equal was just an unnecessary restriction, and letting them be 0
is useful for the case where the context has had non-zero values set, went
over hi_water and called the callback, and then wanted to remove limits
(perhaps because of a reconfiguration).  This allows the callback to
be signaled as ISC_MEM_LOWATER on the next isc_mem_put(), which the caller
might need to terminate any outstanding action that was triggered by
the hi_water.

d76b6ae2ad isc_print_vsnprintf() could throw an assertion failure when 
given a %lld format, causing a deadlock when logging the assertion if invoked
from the logging system.  Since the %qd format does not have the bug, this only
affects platforms where the native quad format is %lld and that lack a native
vsnprintf().  The only known such platform is SunOS 5.5.1. [RT #1312]

5e194abb5b 814. [bug] Socket objects left over from accept() failures 
were incorrectly destroyed, causing corruption
                        of socket manager data structures.

 813.   [bug]           File descriptors exceeding FD_SETSIZE were handled
                        badly. [RT #1192]

2b5f436aeb Make greatest_version() return an isc_result_t, which it should have 
been doing all along since there was the possibility isc_dir_open() would
fail and overloading the return value of "0" was bad practice.

If isc_dir_open() fails in greatest_version(), make sure the path separator
is restored to the destination pathname if it was NULified before returning
the error.

The underlying problem of isc_log_open() not having the bad result of
isc_dir_open() reported anywhere will be slightly mediate by a change
to bin/named/logconf.c to test the directory.  lib/isc/log.c can't really
handle it because it has no idea to where such an error should be reported,
and it only shows up during isc_log_open() as part of the isc_log_write()
family of calls, which are all void.

79ed194592 sigh. always test recompile things even after a minor change. after deciding 
to _not_ much with the lock tracing/printing facility for the last change,
i forgot to also add the new result variable back into the stack
declarations, where i had correctly put it the first time.

a84cfaa3f2 The bug fix in socket.c 1.189 was less than ideal: if a socket 
got wedged in a state where accept() always returns EBADF, the server would loop calling
internal_accept() repeatedly.  Implemented an alternative fix where a hard
error in accept() causes an event with a nonzero result code to be sent, and
the new socket object to be freed

2eb3dafdcf Add the socket flag ISC_R_NORETRY, which makes the socket code treat 
a soft error as a hard error on send (that is, not retry it).  It also
modifies the code calling sendmsg() to retry on EINTR.
