The PostTraversalTask does not take a strong reference to the FontFaceSet
object, since as a DOM object, we can't call AddRef/Release on it
from the Servo style worker threads. The FontFaceSet is held on to
by the nsIDocument, and only cleared during cycle collection, which
should not occur between the font metrics request and the
PostTraversalTask running.

clang's -Wcomma warning warns about suspicious use of the comma operator such as between two statements or to call a function for side effects within an expression. In addition to fixing the warnings, replace some char16_t(' ') casts of char literals with shorter UTF-16 character literals u' '.

Since font-language-override can only have a single three-letter tag, and it is
eventually converted to uint32_t while creating gfxFontStyle, we should be able
to move the conversion ahead, to an earlier stage.
In this patch, we move the ParseFontLanguageOverride to nsRuleNode, so we could
do the nsString-to-uint32_t conversion during computing time.

mDocument is always valid because we get mDocument from the argument of
FontFaceSet's constructor, and FontFaceSet is always created in
nsIDocument's methods.
Delay giving checkTask a name until we dispatch it. No need to name it
twice.

This function is an infallible alternative to nsIURI::GetSpec(). It's useful
when it's appropriate to handle a GetSpec() failure with a failure string, e.g.
for log/warning/error messages. It allows code like this:
nsAutoCString spec;
uri->GetSpec(spec);
printf("uri: %s", spec.get());
to be changed to this:
printf("uri: %s", uri->GetSpecOrDefault().get());
This introduces a slight behavioural change. Previously, if GetSpec() failed,
an empty string would be used here. Now, "[nsIURI::GetSpec failed]" will be
produced instead. In most cases this failure string will make for a clearer
log/warning/error message than the empty string.

Bug 1297961 (part 1b) - More GetSpecOrDefault() additions. r=hurley.
I will fold this into part 1 before landing.
