sterni 5fae8b0826 chore(3p/sources): Bump channels & overlays
* //nix/buildLisp: ccl dumped images have fixed themselves… again

* //3p/git: rebase patch on 2.36.0

* //3p/overlays/haskell: remove upstreamed workarounds

* Disable everything depending on cgit temporarily, since it doesn't
  compile with git 2.36 yet.

# 'impls' is an attribute set of attribute sets which describe how to do common
# tasks when building for different Common Lisp implementations. Each
# implementation set has the following members:
#
# Required members:
#
# - runScript :: string
# Describes how to invoke the implementation from the shell, so it runs a
# lisp file as a script and exits.
# - faslExt :: string
# File extension of the implementations loadable (FASL) files.
# Implementations are free to generate native object files, but with the way
# buildLisp works it is required that we can also 'load' libraries, so
# (additionally) building a FASL or equivalent is required.
# - genLoadLisp :: [ dependency ] -> string
# Returns lisp code to 'load' the given dependencies. 'genLoadLispGeneric'
# should work for most dependencies.
# - genCompileLisp :: { name, srcs, deps } -> file
# Builds a lisp file which instructs the implementation to build a library
# from the given source files when executed. After running at least
# the file "$out/${name}.${impls.${implementation}.faslExt}" should have
# been created.
# - genDumpLisp :: { name, main, deps } -> file
# Builds a lisp file which instructs the implementation to build an
# executable which runs 'main' (and exits) where 'main' is available from
# 'deps'. The executable should be created as "$out/bin/${name}", usually
# by dumping the lisp image with the replaced toplevel function replaced.
# - wrapProgram :: boolean
# Whether to wrap the resulting binary / image with a wrapper script setting
# `LD_LIBRARY_PATH`.
# - genTestLisp :: { name, srcs, deps, expression } -> file
# Builds a lisp file which loads the given 'deps' and 'srcs' files and
# then evaluates 'expression'. Depending on whether 'expression' returns
# true or false, the script must exit with a zero or non-zero exit code.
# 'genTestLispGeneric' will work for most implementations.
# - lispWith :: [ dependency ] -> drv
# Builds a script (or dumped image) which when executed loads (or has
# loaded) all given dependencies. When built this should create an executable
# at "$out/bin/${implementation}".
#
# Optional members:
#
# - bundled :: string -> library
# Allows giving an implementation specific builder for a bundled library.
# This function is used as a replacement for the internal defaultBundled
# function and only needs to support one implementation. The returned derivation
# must behave like one built by 'library' (in particular have the same files
# available in "$out" and the same 'passthru' attributes), but may be built
# completely differently.
