As per #30645, fish with fish-foreign-env prints this
(harmless) warning:
```
set: Tried to change the read-only variable “_”
```
This patch was developed by @rnhmjoj in the aforementioned
issue discussion
partially reverts bfe9c928c1 by author's request, since many modules
are currently broken. 4.14 will be the default kernel when the dust
settles
track github issue #31640
In bfe9c928c1 the default kernel has been
updated to version 4.14 and the declarations for allow_signal() and
signal_pending() are no longer exposed via kthread.h, so let's actually
use the right header files.
I've added a condition for kernel 4.10 and upwards to include the
linux/sched/signal.h header file, because that got introduced in version
4.10. Even if the declaration would still reside in kthread.h (I haven't
checked) for version 4.10 it won't hurt and the compilation will still
succeed.
Tested against kernel 4.9 and 4.14 and the build now succeeds.

Comparing packages via equality will lead to different results when package and module are from different
`nixpkgs` checkouts.
Also, because MariaDB is actually supported, added a note to option description to make this knowledge more discover-able.
`nixos-option` evals the description and the '`' is used to
define shell commands.
Due to this, the following error appears:
```
$ nixos-option services.postgresql.superUser
Value:
"root"
Default:
"root"
Description:
/run/current-system/sw/bin/nixos-option: line 294: root: command not found
/run/current-system/sw/bin/nixos-option: line 294: postgres: command not found
NixOS traditionally used as superuser, most other distros use .
From 17.09 we also try to follow this standard. Internal since changing this value
would lead to breakage while setting up databases.
```
I have also updated the dependencies for bitcoin:
* qt4 is updated to qt5
* miniupnpc 1 is updated to miniupnpc 2
* zeromq dependency has been added to enable ZeroMQ support.
