The cacert package can now generate p11-kit-compatible output itself,
as well as generating the correct set of outputs for fully-joined
and unbundled "traditional" outputs (in standard PEM and
OpenSSL-compatible formats).
According to the ABNF grammar for PEM files described in [RFC
7468][1], an eol character (i.e. a newline) is not mandatory after the
posteb line (i.e. "-----END CERTIFICATE-----" in the case of
certificates).
This commit makes our CA certificate bundler expression account for
the possibility that files in config.security.pki.certificateFiles
might not have final newlines, by using `awk` instead of `cat` to
concatenate them. (`awk` prints a final newline from each input file
even if the file doesn't end with a newline.)

Previously, the list of CA certificates was generated with a perl script
which is included in curl. As this script is not very flexible, this commit
refactors the expression to use the python script that Debian uses to
generate their CA certificates from Mozilla's trust store in NSS.
Additionally, an option was added to the cacerts derivation and the
`security.pki` module to blacklist specific CAs.
There is no "standard" location for the certificate bundle, so many
programs/libraries have various hard-coded default locations that
don't exist on NixOS. To make these more likely to work, provide
some symlinks.
It's more standard than $OPENSSL_X509_CERT_FILE (which I guess was a
totally unnecessary patch to OpenSSL). Since curl respects
$SSL_CERT_FILE, it's no longer needed to set $CURL_CA_BUNDLE. Git
unfortunately doesn't.
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
This change does two things:
* "NixOSizes" environment variables generation. This allows some more
error-checking and opens possibilities for a modular environment
configuration. From now on the most of environment variables are
generated directly by the nix code. Generating sh code that
generates environment variables is left in a few places where
nontrivial access to a local environment state is needed.
* By doing the first change this patch untangles bash from the
environment configuration and makes it trivial to add a support for
other non bash-compatible shells.
Now to the sad part. This change is quite large (and I'm not sure it's
possible to split it) and yet is not quite complete, it needs some
changes to nixpkgs to be perfect.
See !!! comments in modules/config/shells-environment.nix.
Main principle behind this change is "change environment generation
and nothing else". In particular, shell configuration principles stay
exactly the same as before.
NixOS and Fedora uses .../ca-bundle.crt. Ubuntu uses
.../ca-certificates.crt. Add .../ca-certificates.crt symlink to be
compatible with Ubuntu.
Example use case: Bob has a ~/.msmtprc file that he brings over from
Ubuntu. It also works on NixOS.
the CURL_CA_BUNDLE environment variable. This allows curl to work
without the `-k' flag on https sites with a properly signed
certificate.
