Change mozilla::Smprintf and friends to return a UniquePtr, rather than
relying on manual memory management. (Though after this patch there are
still a handful of spots needing SmprintfFree.)

There's an antipattern where nsLiteralString is used as an unnecessary intermediary in converting from CharT* to CharT*,
e.g. CallAFunctionThatTakesACharPointer(NS_LITERAL_CSTRING("foo").get());
or
NS_NAMED_LITERAL_STRING(foo, "abc");
CallAFunctionThatTakesACharPointer(foo.get());
This patch rewrites the callsites that can be trivially changed to use char*/char16_t*.
I'd somewhat like to remove nsTLiteralString::get() altogether, but in code that's less straightforward than these examples, get() is useful enough to keep.

Changed |print("enum ID : uint32_t {", file=output)| to |print("enum HistogramID : uint32_t {", file=output)| at line 53 of the file |toolkit/components/telemetry/gen-histogram-enum.py|, and then replaced all the textual occurrences of |Telemetry::ID| to |Telemetry::HistogramID| and |ID| to |HistogramID| in 43 other files.
nsIXPCScriptable flags handling in xpc_map_end.h is a bit of a mess.
- Half the flags relate to whether various functions are defined (PreCreate,
GetProperty, etc). These are set using the XPC_MAP_WANT_* macros;
for each one xpc_map_end.h inserts the corresponding flag using the
preprocessor (see XPC_MAP_CLASSNAME::GetScriptableFlags()).
- The other half of the flags relate to other things (IS_GLOBAL_OBJECT,
DONT_REFLECT_INTERFACE_NAMES, etc). These are set using the XPC_MAP_FLAGS
macro.
Having two similar but different mechanisms to set the flags for a class is
confusing. (Indeed, until recently we had some classes where a single flag was
redundantly specified via both mechanisms.) Note also that the classes done in
dom/base/nsIDOMClassInfo.h also specify all the flags in a single value,
similar to how XPC_MAP_FLAGS works.
This patch removes the XPC_MAP_WANT_* macros. All flags are now set
via XPC_MAP_FLAGS. This is a significant simplification to xpc_map_end.h and
all the places that use it.
The downside of this change is that I had to change the flag constants from
class constants (i.e. nsIXPCScriptable::FOO) to macros (i.e.
NSIXPCSCRIPTABLE_FOO) because they need to be used in #if statements like this
in xpc_map_end.h:
#if !((XPC_MAP_FLAGS) & NSIXPCSCRIPTABLE_WANT_PRECREATE)
and you can't use a '::'-qualified name inside a #if. I think this downside is
outweighed by the simplification described above.
Overall the patch removes 80 lines of code.
This change is mostly straightforward, except for the following.
- It removes all the printing from the do_check_* macros because gtest macros
do appropriate printing.
- test_StatementCache.cpp needs some special gtest magic for the type
parameterization.
- It merges the four tests in test_unlock_notify.cpp because they rely on being
executed in order, and so aren't independent.
- storage_test_harness_tail.h is no longer necessary because gtest provides the
test looping functionality.
- It uses #include and the preprocessor to remove the duplication between
test_deadlock_detector.cpp and xpcom/tests/DeadlockDetector.cpp.
- It makes the test in test_service_init_background_thread.cpp a death test to
force it to be the first storage gtest, because it fails otherwise.
- It adds code to undo the SQLite mutex hooking as necessary, so that tests
don't interfere with each other.
- It de-virtualizes Spinner's destructor (as identified in bug 1318282).
