This patch essentially creates a separate, static component database for
statically-defined CID and contract ID entries, and gives it precedence over
the runtime DB. It combines the two separate databases by updating existing
code to use lookup functions which understand both databases, and then access
all entries through wrappers which defer to the appropriate underlying type.
Static component entries require no runtime relocations, and require no
writable data allocation aside from one pointer-sized BSS entry per CID, and
one bit of BSS per contract ID.
To achieve this, all strings in the static lookup tables are stored as indexes
into a static string table, all constructor functions live in a switch
statement which compiles to a relative jump table, and all writable data for
static entries is accessed by indexed lookups into BSS arrays.
We also avoid creating nsIFactory entries for static components when possible
by adding a CreateInstance method to nsFactoryEntry and the corresponding
entry wrapper to directly call the appropriate constructor method, and only
create a factory object when required by external code.

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

With the old process selector service implementation, non-cached loads
would skip the call into the process selector.
This implementation piggybacks atop the existing 'redirectTo' mechanism.
This is unfortunately not the perfect system for catching these loads,
as it doesn't provide an opportunity for performing a final process
switch before redirecting to a non-http channel. In addition, it doesn't
provide indication that a redirect is going to happen, causing
potentially unnecessary process switches.
Not all places where 'redirectTo' is supported use this mechanism. This
process switching mechanism is only checked in situations after
http-on-examine-response.
Potential future changes include:
1. Moving these checks closer to the real 'OnStartRequest' call (e.g.
in ContinueProcessNormal + ContinueOnStartRequest3). This would mean
that loads other than the final load will not cause process swaps.
2. Adding a callback before a redirect is performed, passing in the new
channel, and allowing modifications to be made. This would allow
performing a process swap before redirecting to a non-http(s)
channel.

This is needed because early in a content process's lifecycle, NeckoParent may
not have been created yet. This leads to issues when trying to redirect into a
fresh process which hasn't performed network loads yet. By sending the message
over PContent, we can be sure the APIs are available.

1. This patch somehow sets a "breakpoint" in ProcessPartialContent() and ProcessNotModified() to really stop doing things after ProcessPartialContent() and ProcessNotModified(), when the channel is suspended.
2. Add a test for this.

Test steps:
1. Register the observers for http-on-modify-request and http-on-before-connect.
2. There are 3 cases to be tested.
- suspend in http-on-modify-request
- suspend in http-on-before-connect
- suspend in both observers
3. See if the channel can be resumed correctly.

This adds a way to simulate failed network connections, allowing the addition of test coverage that would otherwise not be available. This is used in the Downloads tests to ensure that failures at the network level are handled correctly.

The test intermittently fails on OSX. For some reason start(PORT) doesn't always fail when PORT is in use, so we timeout because the handler is never called. I suspect it's because of how SO_REUSEADDR and SO_REUSEPORT are handled on sockets sever-side on OSX. Since httpd is used for unit tests, there is little risk in disabling the test on OSX.
The alternative is to check for a timeout, and in that case switch to another port - which is cumbersome, and not the purpose of the test.
