Fix to CONST with the math evaluator to toss a message and error with values out of acceptable range for ARCSEC and ARCCSC.
Tweak to _PI to add constexpr for speedier execution.
Fix to the math tests for the new (and unbuggy) values for ARCSEC and ARCCSC.
Fairly simple, MacOS High Sierra's libcurl version is too old and not
have `CURLINFO_CONTENT_LENGTH_DOWNLOAD_T`. This adds a version check to
use the older version of that command which gives back a double instead.

Currently main() includes logic that is intended to sync time() with
GetTicks() for the purpose of using GetTicks() to get millisecond
accuracy with time(), which only has second accuracy. Unfortunately, the
'syncing' up of these time sources results in an average of a half
second delay in starting a QB64-PE program.
This logic is easly replaced with std::chrono, which provides a real
time clock which is also millisecond accurate. That removes the need to
use time() and GetTicks() together to get millisecond accuracy, and
means the delay syncing them is no longer necessary.
I also separated most of the "delay" and "time" related functions into
datetime.cpp, and included the new std::chrono code into that file.
Since I needed to call some of the rounding functions in datetime.cpp I
also moved that stuff out into its own .cpp and header files to clean
things up a bit.

Fairly simple, the finished entry is free'd and then removed from the
list, but that order results in us accessing the entry's next member
after it has been free'd. Swapping the order of the operations fixes the
issue.

The commands _ScreenX and _ScreenY got significantly slower due to the
need to wait for the GLUT thread to wake up and execute the glutGet()
command for them. We've already seen a few programs (including the IDE)
where this behavior completely grinds the program to a halt, so we
definitely can't keep it.
The simple solution here is to not call glutGet() on every _ScreenX/Y
command. Instead every time the idle/timer function runs we get the
current values for the relevant glutGet() variables and store them.
libqb_glut_get() then checks if the value being read is one of the ones
we read in the idle/timer functionand if so just returns the last read
value. By doing it this way the commands no longer has to wait on the
GLUT thread for the result.
