Bug 1412187 - ChannelMediaResource::Resume() should call Seek() instead of CacheClientSeek(). r=gerald

CacheClientSeek() will call Seek() asynchronously and should be used by MediaCache only.
ChannelMediaResource::Resume() runs on the main thread and can call Seek() directly.
Note this is a missing change from bug 1411504 P3.

Bug 1410794 (attempt 2) - Change some |string| occurrences in nsIPrefBranch.idl to |ACString|. r=erahm.

This makes the code nicer. In particular, it removes many getter_Copies()
calls. The patch also converts a lot of nsCStrings to nsAutoCString, which will
avoid heap allocation in the common case.

The patch also renames PREF_CopyCharPref() as PREF_GetCStringPref(), because
it's actually getting a string, not a char, and that matches the existing
GetCString() and GetDefaultCString() methods. Correspondingly, it also renames
PREF_SetCharPref() as PREF_SetCStringPref().

The |aPrefName| arguments in nsIPrefBranch.idl remain as |string| because they
almost always involve passing in C string literals, and passing "foo" is much
nicer than passing NS_LITERAL_CSTRING("foo").

It's worth noting that early versions of this patch used |AUTF8String| instead
of |ACString|. But it turns out that libpref stores prefs internally as Latin1.
And |ACString| is compatible with Latin1 but |AUTF8String| isn't, because
non-ASCII Latin1 strings are not valid UTF-8!

- Building is nightly channel only.  Beta and release for Fennec 58 don't build
  stylo.  It means that the package size for 58 beta/release isn't incremented
  by this change.
- The preference for stylo is still turned off Nightly 58. It will be turned on
  59 after fixing some bugs for crashtests and etc.  Our target to enable stylo
  for Android is 59.
- ./mach bootstrap already installs clang etc to build stylo and bindgen.
  Developers for mobile won't require additional build options for this change.
