CMP0054: Remove ALLOWED_UNKNOWN_VARIABLE_READ_ACCESS

The CMake code for it is now redundant and only slows down uninitialized
variable accesses.

CTEST: Fix MUMPS coverage parsing and test

Fix the MUMPS coverage parser:
 Account for tabs after entry points
 Stop double incrementing lines that have explicit calls to the 0 line
 If a line has been previously marked as non executable, but then contains a
  count, increment it an extra one to push it back into the executable code set.

Add a custom routine and corresponding coverage files.  This file is smaller
and has cmcov/mcov files that have data for only that routine.

CTEST: Remove old VistA-FOIA directory before copying

Ensure that the directory that holds the MUMPS code is removed before
copying the test routines into it.  Ensures that the old routines aren't left
behind.

62a4a67d Add the WriteCompilerDetectionHeader module.
Add the WriteCompilerDetectionHeader module.

Provide a function to write a portable header to detect compiler
features.  Generate a preprocessor #error for unknown compilers
and compiler versions whose features are not yet recorded.  This
error condition might be relaxed in the future, but for now it
is useful for verification of expectations.

Features: Extend concept to C language.

Add properties and variables corresponding to CXX equivalents.

Add features for c_function_prototypes (C90), c_restrict (C99),
c_variadic_macros (C99) and c_static_assert (C11). This feature
set can be extended later.

Add a <PREFIX>_RESTRICT symbol define to WriteCompilerDetectionHeader
to conditionally represent the c_restrict feature.
