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.
