Brad King 0fe4d8bb3b ExternalData: Add support for custom download scripts
Add support for a special URL template to map the fetch operation
to a project-specified .cmake script insead of using file(DOWNLOAD).

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

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.

Brad King 8eb20eeabe ExternalData: Allow local stores without any URL templates
Allow ExternalData_URL_TEMPLATES to be empty if a value for
ExternalData_OBJECT_STORES is provided.  Assume in this use case that
the object stores will already contain all needed objects.  Extend the
Module.ExternalData test to cover this case (all objects in stores).
Extend the RunCMake.ExternalData test to cover the non-failure message
case when stores are provided without URL templates.

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.

Brad King 55f0148d7b ExternalData: Test content link with a space in its name
Extend the Module.ExternalData test to cover a DATA{} reference whose
name contains a space.  Skip the case when the native build tool does
not support spaces.

Brad King aed590a7e0 Fix Module.ExternalData test on Cygwin
In ExternalData_URL_TEMPLATES add a leading slash to the path after
file:// only if the path does not already start with one.

Brad King ee2abfdc89 ExternalData: Add support for SHA 1 and 2 hash algorithms
Update the Module.ExternalData and RunCMake.ExternalData tests to cover
some of them.

Brad King 9e518a8169 ExternalData: Allow DATA{} syntax to reference directories
Use a trailing slash to reference a directory.  Require that a list
of associated files be specified to select from within the directory.
One may simply use DATA{Dir/,REGEX:.*} to reference all files but
get a directory passed on the command line.

Brad King 4befecc77c ExternalData: Add tests covering interfaces and errors
Add a Module.ExternalData test to verify data retrieval and test
argument DATA{} references.

Add a RunCMake.ExternalData test to verify error handling and automatic
transformation of a raw data to a content link and staged object.
