This changeset is the result of adding modernize-use-default-member-init to
tools/clang-tidy/config.yaml then proceeding to run
`./mach static-analysis check netwerk/ --fix`
I then went through the resulting fix and manually updated all of the member
variables which were missed due to them having a non-trivial constructor.
Note that the tool was only run on Linux, so code that only runs on some
platforms may have been missed.
The member variables that are still initialized in the contructor definition
are:
- bitfields (not all currently supported compilers allow default-member-init
- variables that are initialized via a parameter
- variables that use code not visible in the header file
There are a few advantages to landing this change:
- fewer lines of code - now declaration is in the same place as initialization
this also makes it easier to see when looking at the header.
- it makes it harder to miss initializing a member when adding a new contructor
- variables that depend on an include guard look much nicer now
Additionally I removed some unnecessary reinitialization of NetAddr members
(it has a constructor that does that now), and changed nsWifiScannerDBus to
use the thread-safe strtok_r instead of strtok.

Stuff that's infallible and not virtual has no reason to return an nsresult.

This patch tries to move them to `ContentParent` instead.
`ProcessPriorityManagerImpl::ObserveContentParentCreated` could not be moved
due to using `do_QueryInterface` to cast from a `nsISupports` down to the
`ContentParent` object. This could be fixed to remove the interfaces entirely,
but I left that for a follow-up.
Depends on D20549

The total size of an IPC inputStream message must be less than 1mb. When we
compose the message for the multiplex stream, each sub stream collaborates with
its own size, deciding if it's better to be a pipe stream (IPCRemoteStream) or
a full serialized one.

Before this set of patches, the decision of exposing the stream as a pipe was
centralized in IPCStreamUtils, based on the total expectation size of the IPC
message. This triggers issues when multiplex inputStreams contain something
that cannot be sent as a pipe (IPCBlobInputStream, for instance), or something
that it's better to do not set as a pipe (nsFileInputStream), together with
memory streams (nsStringInputStream), which could make the IPC message greater
then what accepted (1mb).
These patches move the "pipe vs non-pipe" choice into the single inputStream
implementation.
In the current code there are 3 main issues:
1. nsFileStream is not really thread-safe. There is nothing to protect the
internal members and we see crashes.
2. nsPipeInputStream doesn't implement ::Seek() method and that caused issues
in devtools when a nsHttpChannel sends POST data using a pipe. In order to fix
this, bug 1494176 added a check in nsHttpChannel: if the stream doesn't
implement ::Seek(), let's clone it. This was an hack around nsPipeInputStream,
and it's bad.
3. When nsHttpChannel sends POST data using a file stream, nsFileStream does
I/O on main-thread because of the issue 2. Plus, ::Seek() is called on the
main-thread causing issue 1.
Note that nsPipeInputStream implements only ::Tell(), of the nsISeekableStream
methods. It doesn't implement ::Seek() and it doesn't implement ::SetEOF().
With this patch I want to fix point 2 and point 3 (and consequentially issue 1
- but we need a separate fix for it - follow up). The patch does:
1. it splits nsISeekableStream in 2 interfaces: nsITellableStream and
nsISeekableStream.
2. nsPipeInputStream implements only nsITellableStream. Doing this, we don't
need the ::Seek() check for point 2 in nsHttpChannel: a simple QI check is
enough.
3. Because we don't call ::Seek() in nsHttpChannel, nsFileStream doesn't do I/O
on the main-thread, and we don't crash doing so.
This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.
