Tidy (#41)

* Deduplicate common constants into OPM and do some source format tidying.

* Fix postpush buildall script to force checkout of updated buildall.

* Show enlistment branch in makefiles

* Support non-printables in string literals and tidy case alignment and constant literals.

* Common code for MIN and MAX of integer types.

* Common code for SInt/Int/LInt in ConstOp parameter preparation.

* Common code for SInt/Int/LInt in Op parameter preparation.

* Refactor SetIntType to work with byte size directly. Prepare to revert my incorrect VAL changes.

* Original meaning of VAL restored. Many library files disabled until use of VAL in 64 bits fixed.

* Make Reals.Mod independent of INTEGER size and add reals tests.

* Implement fraction, IsInfinity and IsNaN in oocLowReal.Mod.

* OPB little simplifications and ShorterSize/LongerSize functions.

* Add test for alignment computability

* Replace alignment constants with calculated alignment.

* typ.size aware OPV.Convert

* Add SYSTEM_INT64 and make tests name independent.

* Remove SYSTEM.H includes (string.h and stdint.h).

* Replace uses of uintptr_t and size_t with SYSTEM_ADDRESS.

* Sad hack to make FreeBSD and OpenBSD happy with memcpy declaration.

* Detect 64 bit on FreeBSD, and size_t defined on OpenBSD.

* %zd not supportd by mingw, cast strnlen return to int.

* Add debug for intermittent failure only on OpenBSD.

* Add textTexts as a confidence test and tidy up a couple of other tests.

* Update binary test process.
