This also removes any redundant Ci.nsISupports elements in the interface
lists.

This patch the list of process and crash types that can be recorded in a keyed
histogram by the crash manager; the relevant pattern was updated to match
these kesy. A test was also added to ensure that no new crash types can be
added without also updating Histograms.json. This also fixes a related
existing test.

This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <![CDATA[, """ or '''. The first two
cover comments, the third one covers JS, the fourth covers JS embedded
in XUL, and the final two cover JS embedded in Python. This also
applies if the removed line was the first line of the file.
It covers the pattern matching cases like "var {classes: Cc,
interfaces: Ci, utils: Cu, results: Cr} = Components;". It'll remove
the entire thing if they are all either Ci, Cr, Cc or Cu, or it will
remove the appropriate ones and leave the residue behind. If there's
only one behind, then it will turn it into a normal, non-pattern
matching variable definition. (For instance, "const { classes: Cc,
Constructor: CC, interfaces: Ci, utils: Cu } = Components" becomes
"const CC = Components.Constructor".)

This marks **/docs/** as exclusively docs, and code that is autodoc'd as
inclusively docs.
That means that a change that purely modifies documentation files will *only*
run `docs` tasks, while a change that modifies autodoc'd source code will
*additionaly* run `docs` tasks. The tasks do not run by default.

At present it is difficult to determine whether a crash ping is from a
shutdownkill or not. By including ipc_channel_error we will be able to figure
that out.
We also as a bonus get additional insight into ipc channel error types that
lead to crashes.

This solves two problems that were causing tests to fail intermittently. The
first issue is that calling nsIProcess.kill() on a process that had already
terminated would throw an exception which wouldn't be caught. Since this might
happen in cases where the minidump-analyzer run significantly faster than the
main event loop during the test. The second issue is that we tried to
unconditionally escape both the 'TelemetryEnvironment' and 'StackTraces'
field, but the latter would not be present in cases where the
minidump-analyzer would fail or be killed. This led to another spurious
exception.

This adds an attribute 'noShell' to nsIProcess that is used to launch a process
using CreateProcess() if we are sure we are launching an executable and don't
require the extra work of the Windows shell service.

When a content crash is detected we run the minidump analyzer on it to extract
a stack trace that will be sent with the crash ping. Since this operation can
potentially take a long time this patch prevents it from happening if the
browser is already quitting. Already running instances of the minidump
analyzer are also killed. The patch includes test coverage for both the new
codepaths.

This adds the RemoteType annotation to a content crash report so that we can
distinguish between content processes that crashed while running remote, local
or extension code. The annotation is passed along the others to Socorro by the
crashreporter and is also whitelisted for inclusion in the crash ping.

This patch removes the C++ code used to run the minidump analyzer when a
content process crashes, and replaces it with JS code within the CrashService
object. This removes the need for a separate shutdown blocker in C++ code and
allows end-to-end testing of the crash service functionality. Additionally
the exception handler code can be simplified since it's now only used to run
the crash reporter client.
The test added to test_crash_service.js covers computing the minidump SHA256
hash (bug 1322611) and of the minidump analyzer itself (bug 1280477).

Currently we hand over a crash ping to the pingsender via a pipe; if the
pingsender fails to send the ping we rely on the CrashManager assembling and
sending one instead. Since the crashmanager is not aware of whether the ping
was sent or not this causes duplication on the server side. To solve this
problem we save the ping to disk instead, read it from the pingsender and
delete the file only if the ping was sent. In this scenario the CrashManager
will know that a ping was already sent and will not send a new one.
This patch removes all the code used to deal with pipes between the telemetry,
crashreporter and pingsender code and also tries to cut down the amount of
platform-specific code we have in this machinery.

This patch changes the crashreporter client code as well as the crash service
code to compute a SHA256 hash of a crash' minidump file and add it to the
crash ping. The crash service code computes the hash on the fly before handing
over the crash to the crash manager; the crash manager will then add it to the
crash ping. The crashreporter client on the other hand sends the hash via the
ping it generates but it also adds it to the event file so that the crash
manager can pick it up and send it along with its own crash ping. On Fennec
the crashreporter activity takes care of computing the hash.
SHA256 hash computation uses nsICryptoHash in the crash service, the
java.security.MessageDigest class in Fennec, the bundled NSS library in the
crashreporter when running on Windows and Mac and the system-provided NSS
library under Linux. The latter is required because the crashreporter client
uses the system curl library which is linked to NSS and which would thus clash
with the bundled one if used together.
This patch introduces two new methods for the nsICrashService interface:
|getMinidumpForID()| and |getExtraFileForID()|, these reliably retrieve the
.dmp and .extra files associated with a crash and ensure the files exist
before returning. These new methods are used in the CrashService for
processing and will become the only way to reliably retrieve those files
from a crash ID.
