This allows MOZ_TRY and MOZ_TRY_VAR to be transparently used in XPCOM methods
when compatible Result types are used.
Also removes a compatibility macro in SimpleChannel.cpp, and an identical
specialization in AddonManagerStartup, which are no longer necessary after
this change.

We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

The macro simultaneously declares an enumeration and a count of its
enumerators.
A few variants of the macro are also provided to handle things like
enum classes, underlying types, and enumerations declared at class
scope.

We needed this polyfill for <initializer_list> when some of our C++
standard libraries did not support said header. They all do now, so the
polyfill is redundant.
With this change, we could share this EnumTypeTraits between files easily.

The default placement operator new is defined to always require that its
result be null-checked. A sufficiently smart compiler can remove this
check, but not all compilers are sufficiently smart. Better to have a
custom placement operator new that will remove null checks in a way
defined by the standard.
This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

This patch implements mozilla::NotNull, which is similar but not identicial to
gsl::not_null.
The current draft(?) implementation of gsl::not_null is at
https://github.com/Microsoft/GSL/blob/master/include/gsl.h.
The main difference is that not_null allows implicit conversion from T to
not_null<T>. In contrast, NotNull only allows explicit conversion from T to
NotNull<T> via WrapNotNull().
The rationale for this is that when converting from a less-constrained type to
a more constrained type, implicit conversion is undesirable. For example, if I
changed a function f from this:
f(int* aPtr);
to this:
f(gsl::not_null<int*> aPtr);
no call sites would have to be modified. But if I changed it to this:
f(mozilla::NotNull<int*> aPtr);
call sites *would* need to be modified. This is a good thing! It forces the
author to audit the call sites for non-nullness, and encourages them to
back-propagate NotNull throughout the code.
The other difference between not_null and NotNull is that not_null disables
pointer arithmetic, which means it cannot be used with array pointers. I have
not implemented this restriction for NotNull because it seems arbitrary and
unnecessary.
The current implementation of HierarchicalStringList allows the following:
FOO.bar = [
'foo',
'bar',
]
while
FOO.bar += [
'foo',
'bar',
]
would be invalid because of the StrictOrderingOnAppendList enforcement.
It also allows to overwrite the entire list with a subsequent
FOO.bar = [
'baz',
]
while we've explicitly forbidden such things for every other list.
While in the vicinity, fix HierarchicalStringList._get_export_variable to not
call the HierarchicalStringList constructor uselessly.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.

Various bits depend on RefPtr.h to provide RefCounted<T> and RefPtr<T>.
It will be easier to manage an automatic conversion from RefPtr<T> to
nsRefPtr<T> if we split out the dependency on RefCounted<T> first.
The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.
