* fixup! silence spurious alignment warning
* use -w for DISABLE_WARNINGS in Clang
* refactor: fix libtransmission deprecation warnings
* fix: pthread_create's start_routine's return value
This was defined as `void` on non-Windows but should have been `void*`
* chore: uncrustify
* fix: add DISABLE_WARNINGS option for SunPro Studio
* fix "unused in lambda capture" warnings by clang++
* fix 'increases required alignment' warning
Caused from storing int16_t's in a char array.
* fix net.c 'increases required alignment' warning
The code passes in a `struct sockaddr_storage*` which is a padded struct
large enough for the necessary alignment. Unfortunately it was recast as
a `struct sockaddr*` which has less padding and a smaller alignment. The
warning occrred because of these differing alignments.
* make building quieter so warnings are more visible
* fixup! fix 'increases required alignment' warning
* Fix -Wcast-function-type warnings in GTK+ app code
https://gitlab.gnome.org/GNOME/gnome-terminal/issues/96 talks about both
the issue and its solution.
GCC 8's -Wcast-function-type, enabled by -Wextra, is problematic in glib
applications because it's idiomatic there to recast function signatures,
e.g. `g_slist_free(list, (GFunc)g_free, NULL);`.
Disabling the warning with pragmas causes "unrecognized pragma" warnings
on clang and older versions of gcc, and disabling the warning could miss
actual bugs. GCC defines `void (*)(void)` as a special case that matches
anything so we can silence warnings by double-casting through GCallback.
In the previous example, the warning is silenced by changing the code to
read `g_slist_free(list, (GFunc)(GCallback)g_free, NULL);`).

Assignments explicitly enclosed in parentheses are ignored.

that yield a Boolean value
* MISRA C++:2008, 6-2-1 - Assignment operators shall not be used in
sub-expressions

* CERT, EXP45-C. - Do not perform assignments in selection statements
* CERT, EXP51-J. - Do not perform assignments in conditional expressions
This way all the qualifiers (`const`, `volatile`, `mutable`) are grouped
together, e.g. `T const* const x` vs. `const T* const x`. Also helps reading
types right-to-left, e.g. "constant pointer to constant T" vs. "constant
pointer to T which is constant".
There're places where manual intervention is still required as uncrustify
is not ideal (unfortunately), but at least one may rely on it to do the
right thing most of the time (e.g. when sending in a patch).
The style itself is quite different from what we had before but making it
uniform across all the codebase is the key. I also hope that it'll make the
code more readable (YMMV) and less sensitive to further changes.
