Brad King f7f4ca55bd ExternalData: Add support for custom algorithm-to-URL mapping
Allow URL templates to contain a %(algo:<key>) placeholder that is
replaced by mapping the canonical hash algorithm name through a map
defined by the <key>.

Extend the Module.ExternalData test to cover the behavior.
Extend the RunCMake.ExternalData test to cover error cases.

Stephen Kelly fb3487a997 Features: Fix C90 feature detection.
This bug caused c_function_prototypes to not be recorded at configure
time when compiling with -std=gnu99 or similar. In the case of feature
recording, that was not a problem, because the logic in
CMakeDetermineCompileFeatures.cmake currently assumes that a feature
present for an earlier standard is present for a later standard.

However, the detection strings are also used in WriteCompilerDetectionHeader,
so the feature macro has been defined to '0' when using a later language
dialect.

Fix that by not checking the existence of the __STDC_VERSION__ macro at
all when detecting C90 features.

Stephen Kelly 3c0996c135 WCDH: Test that no C compiler features are defined for CXX compiler.
This amends commit 54156d72 (WCDH: Generate per-language files

Stephen Kelly 8dc0c97666 WCDH: Fix the C_STANDARD property in the tests.
The CXX_STANDARD property validates the values allowed for it,
and '90' is not a valid value for it.  However, the validation is only
done for languages enabled for the target, and as C_undefined has no
CXX files, that language is not enabled for it.

This amends commit v3.1.0-rc3~23^2 (WCDH: Make the header -Wundef
safe for the C language., 2014-11-24).

Robert Maynard f73718c9b8 Features: Enable writing of MSVC compiler feature header.
Notes:
VS2015 and above are the only MSVC versions to support cxx_final, so remove
usages from the tests, and instead only test for cxx_override.

VS2012 and above to conform to cxx_decltype_incomplete_return_types
proposal, but without support for auto return types the dcl.type.simple
example in the proposal doesn't compile.

VS2013 and above to conform to the updated cxx_contextual_conversions proposal,
but VS2010 and above pass the test.

Compilers such as MSVC have no explicit flags to enable C++11 mode,
it just is always on. So only run the link tests with compilers that require
a flag to specify the language version.

Stephen Kelly 62a4a67dc5 Add the WriteCompilerDetectionHeader module.
Provide a function to write a portable header to detect compiler

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.

Rolf Eike Beer b0f277db38 HP aCC: record compiler flag for Ansi C++98 support for version 3.80 onwards
Old versions of aCC need a special compiler flag to get full C++98 template
support as e.g. CMake itself or the Complex and ComplexOneConfig tests need.
The same versions need a special flag to get a proper C++ library, too.

Brad King ccd29b9af8 ExternalData: Warn on missing file instead of failing
When the primary source tree path named by a DATA{} reference does not
exist, produce an AUTHOR_WARNING instead of a FATAL_ERROR.  This is
useful when writing a new DATA{} reference to a test reference output
that has not been created yet.  This way the developer can run the test,
manually verify the output, and then copy it into place to provide the
reference and eliminate the warning.

If the named source tree path is expected to be a file but exists as a
directory, we still need to produce a FATAL_ERROR.

Stephen Kelly 7e24997fed GenerateExportHeader: Generate only C identifiers as defines
The variables in this module are used to configure a header file
with defines whose name depends on the name of the target.

As valid names of targets may be invalid for use as defines, convert
the names of the defines used to C identifiers first. This is already
done in C++ code for the DEFINE_SYMBOL property.

This is not as simple as ensuring that the BASE_NAME is a C identifier,
because most of the define names are configurable, and because use of
a BASE_NAME which is not a C identifier, such as 4square can become a
C identifier by specifying a prefix in the generate_export_header
macro.

Brad King 1823ab4d76 ExternalData: Preserve escaped semicolons during argument expansion
The CMake language implicitly flattens lists so a ";" in a list element
must be escaped with a backslash.  List expansion removes backslashes
escaping semicolons to leave raw semicolons in the values.  Teach
ExternalData_Add_Test and ExternalData_Expand_Arguments to re-escape
semicolons found in list elements so the resulting argument lists work
as if constructed directly by the set() command.

For example:

  ExternalData_Add_Test(Data NAME test1 COMMAND ... "a\\;b")
  ExternalData_Expand_Arguments(Data args2 "c\\;d")
  add_test(NAME test2 COMMAND ... ${args2})

should be equivalent to

  set(args1 "a\\;b")
  add_test(NAME test1 COMMAND ... ${args1})
  set(args2 "c\\;d")
  add_test(NAME test2 COMMAND ... ${args2})

which is equivalent to

  add_test(NAME test1 COMMAND ... "a;b")
  add_test(NAME test2 COMMAND ... "c;d")

Note that it is not possible to make ExternalData_Add_Test act exactly
like add_test when quoted arguments contain semicolons because the CMake
language flattens lists when constructing function ARGN values.  This
re-escape approach at least allows test arguments to have semicolons.

While at it, teach ExternalData APIs to not transform "DATA{...;...}"
arguments because the contained semicolons are non-sensical.
