Bug 517580 - Unconditionally build with support for getters and setters, remove support for the deprecated { x getter: function() {}} and x getter= function() {} getter syntaxes (mutatis mutandis for setter) now that ES5 provides Object.getOwnPropertyDescriptor and Object.defineProperty and { get x() { } } syntax, and provide __{define,lookup}{G,S}etter__ only if a preprocessor variable is defined (unconditionally provided for the moment). r=luke

Bug 515233: Widen JSTreeContext::flags to 32 bits. r=igor
...
All the bits in this uint16 field are currently in use. Adding bits
for projects like strict mode entails relocating existing flags, which
is additional work. Furthermore, it seems that this has already
inspired people to put flags in places they don't belong:
TSF_DESTRUCTURING is a JSTokenStream flag, but is only used by the
parser.
This patch widens the field to 32 bits, and adjusts JSFunctionBox and
a few other places to match.
We should really replace these all with bitfields.

Bug 515233: Make the static level its own parameter to JSCompiler::compileScript. r=igor
...
Pre-patch, the initial static level at which a script should be
compiled to run is passed in the upper sixteen bits of the tcflags
parameter to JSCompiler::compileScript; because JSTreeContext::tcflags
is a uint16, while the tcflags parameter is a uint32, we know the
parameter's upper bits are free.
However, we would like to enlarge JSTreeContext::tcflags to 32 bits,
as we already have a handful of new flags that belong there. This
patch moves the static level to its own parameter, which has a default
argument.

Bug 97954: Give jsconfig.h a better name, and make room for the new js-config.h. r=bsmedberg
...
We'd like the SpiderMonkey configure script to generate a header file
named js-config.h to hold #definitions chosen at configure time that
affect the SpiderMonkey API, like JS_THREADSAFE. However, that name
is very similar to that of an existing header file, jsconfig.h. This
patch renames the existing header file, and updates all references to
it.
