In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

This was added in 2005 back in r51ce4ea2. This was not commented or
explained anywhere, and it does not seem to be necessary anymore
according to some quick testing I did.
Reduces mono closure size by ~100M.
This was introduced in 2010 in 9e16b812 and as far as I can tell the
issue mentioned in the comment does not exist anymore. In a stripped
mono build, I was able to:
- Run "mcs --version" without trouble (original test case)
- Run "keepass" (mono app)
- Build packages that depend on mono (e.g. f# and others).
$ nix path-info -sh
Before: 537.8M
After: 304.3M
$ nix path-info -Sh
Before: 1.2G
After: 867.0M
(Transitive closure size decreases more than the package size itself
because mono ended up depending on gcc through leaked paths in .so files
before.)
I have checked a couple of times that building in parallel succeedes even with
nix-build --cores 9999, and once that the result can build all not broken
dependent projects.
Closes#58797.
Since years I'm not maintaining anything of the list below other
than some updates when I needed them for some reason. Other people
is doing that maintenance on my behalf so I better take me out but
for very few packages. Finally!
* treewide: http -> https sources
This updates the source urls of all top-level packages from http to
https where possible.
* buildtorrent: fix url and tab -> spaces
