I removed it from the synopsis, and reworded the description to: 1. make
it sound less like marketing, and keeping the single-header thing as a bonus.

I don't know enought about grafts, so I trust you on that.  I did not
know where to put the comment, so I added it at the very top.

I also noticed that this was updated since last time, so I updated it to
0.8.8 (latest tagged version).

Didn't think about that, I wrapped it in a `when tests?` (and added
`tests?` as argument to the lambda) as you suggested.  I also changed it
a bit making it more clear.  There are now tests requiring network
access, so I disabled them.

Sure, added brotli and moved openssl to inputs.  I also aadded the
"HTTPLIB_REQUIRE_" flags just to be sure they are used int the build.
They shouldn't be needed as HTTPLIB_USE_*_IF_AVAILABLE defaults to ON,
but if they change default we are covered.


Regarding why openssl and zlib were in native-inputs, this is (probably)
how it went: I built it without openssl, tests failed to run because the
command openssl was required to generate a certificate, so I added it to
native-inputs.  Then probably I added zlib not noticing I placed it
under native-inputs, at least that's how I think it went.

nheko still builds and run, so here the v5 of the series.
