Content which is incomplete as a generator expression could cause
segfaults by advancing an iterator beyond end() and dereferencing
it. Such incomplete generator expressions should be treated as
plain text instead.
The rationale is similar to that in commit b3d8f5da (GenEx: Parse comma
after colon tokens specially, 2012-10-04), in that colon tokens should
not be parsed as identifier-argument delimiters after the first colon.
Now automoc always uses GetRealPath() so symbolic links are always
resolved and it doesn't end up with twice the same file, once with the real
path and once with the symlinked path in some setups where the source dir
can be accessed directly and via a symlink

7aa9927 GenEx: Don't use std::vector::at(int).
78e54b9 GenEx: Add tests for "0" and "1" expressions with literal commas.
d729e8b GenEx: Add test for $<BOOL:> with empty parameter.
354face GenEx: Ensure that the empty CONFIGURATION can be used conditionally.
8b3b88a GenEx: Validate target and property names.
b3d8f5d GenEx: Parse comma after colon tokens specially
a4985a9 GenEx: Report actual target name not found, not "0" each time.
d70650d GenEx: Return after error reported.
4801eb6 GenEx: It is not an error to specify an empty parameter
Otherwise the comma is treated as plain text by ParseContent.
$<STREQUAL:,> should be valid and true.
$<STREQUAL:,something> should be valid and false.
$<STREQUAL:,,> should be non-valid as it is 3 parameters.
$<STREQUAL:something,,> should be non-valid as it is 3 parameters.
Additionally, this allows reporting the correct error for other
expressions. For example $<TARGET_PROPERTY:,> should be invalid
because it has an empty target and empty property. It shouldn't
attempt to read the property ',' on the 'implicit this' target.
If the checker was explicitely set with a "TypeCommand" variable (e.g.
ValgrindCommand) then we now just believe that this is valgrind, even if
nothing in the path matches "valgrind". Only when "MemoryCheckCommand" was used
we still scan the path to find out what checker we have.
