7598126391 remove separate meta-section, add architecture diagram
the diagram is a first approximation and only covers that same section.
of course there is much more going on, and other features should at some
point also be illustrated.

we also have to think about presentation format and technicalities
behind it. the manual has to render to `man`, but we may want something
more refined for web view.

b387d80943 remove sentence for chapter transition
idea: sections could be read in different orders by linking them in
different ways (e.g. depth-first or breadth-first). adding hard-coded
transitions makes that confusing.

523359d133 WIP: Document the design of Nix
The current docs are all "how to do things" and no "what is Nix" or "why
are things the way they are".

I see lots of misconception on the wider internet, and I also think we
would benefit from a "living document" to answer some questions people
currently turn to the thesis for.

I think a new section of the manual can address all these issues.

- use "Nix language" consistently

649c9d9b4c doc: acknowledge post-rsync reality
Before #5150 the copy-to-store phase of the install was idempotent,
but the recursive cp isn't. This is probably baiting a few people
into trying corrective installs that will fail.

5b8c1deb18 fetchTree: Allow fetching plain files
Add a new `file` fetcher type, which will fetch a plain file over
http(s), or from the local file.

Because plain `http(s)://` or `file://` urls can already correspond to
`tarball` inputs (if the path ends-up with a know archive extension),
the URL parsing logic is a bit convuluted in that:

- {http,https,file}:// urls will be interpreted as either a tarball or a
  file input, depending on the extensions of the path part (so
  `https://foo.com/bar` will be a `file` input and
  `https://foo.com/bar.tar.gz` as a `tarball` input)
- `file+{something}://` urls will be interpreted as `file` urls (with
  the `file+` part removed)
- `tarball+{something}://` urls will be interpreted as `tarball` urls (with
  the `tarball+` part removed)

nix repl: make symlinks with the :bl command
Requested by ppepino on the Matrix:

This adds a new command, :bl, which works like :b but also creates
a GC root symlink to the various derivation outputs.

ckie@cookiemonster ~/git/nix -> ./outputs/out/bin/nix repl
Welcome to Nix 2.6.0. Type :? for help.

2799fe4cdb enable LTO in optimized builds
gives 2-5% performance improvement across a board of tests.
LTO is broken when using clang; some libs link fine while others crash
the linker with a segfault in the llvm linker plugin. 🙁

doc: Add detailed uninstall section for macOS
The multi-user installation on macOS, which is now the only option, has
gotten complicated enough that it discourages some users from checking
Nix out for fear of being left with a "dirty" system. Detailed
uninstallation instructions should make this less of an issue.

00c993f48b add zipAttrsWith primop
nixpkgs can save a good bit of eval memory with this primop. zipAttrsWith is
used quite a bit around nixpkgs (eg in the form of recursiveUpdate), but the
most costly application for this primop is in the module system. it improves
the implementation of zipAttrsWith from nixpkgs by not checking an attribute
multiple times if it occurs more than once in the input list, allocates less
values and set elements, and just avoids many a temporary object in general.

nixpkgs has a more generic version of this operation, zipAttrsWithNames, but
this version is only used once so isn't suitable for being the base of a new
primop. if it were to be used more we should add a second primop instead.

90700736c7 Introduce builtins.groupBy primop
This function is very useful in nixpkgs, but its implementation in Nix
itself is rather slow due to it requiring a lot of attribute set and
list appends.
