Issue #9334 shows that `%` characters on Windows result in invalid
paths, also `/` characters on Linux create invalid paths.

This changes from using base64 to using base16 with the same length
we use for unit-ids.

* Bump base in cabal-dev-scripts.cabal

Bump base in cabal-dev-scripts.cabal. We are now using GHC 9.4.7 in CI, which ships with base 4.17.2.0. I am bumping all the way to <4.19 after testing everything compiles with GHC 9.6.3 (base-4.18.1.0).

* Avoid OverloadedStrings when it causes troubles

# Conflicts:
#	Cabal-syntax/src/Distribution/Fields/Parser.hs

* doctest: provide a separate project file without -Werror (fix #9307)

This became necessary after an upgrade to GHC 9.4, which, apparently,
has a subtle change in how -W/-w-related things get interpreted.

cabal-install: Fix non-reinstallable package set (backport #9092)

cabal-install: Fix non-reinstallable package set

In #9064 we discovered that `ghc-boot` was added to the
non-reinstallable package set due to #8051 despite there being no
reason why it can't be built from its source distribution. This
revealed the fact that there is quite some ambiguity around what
constitutes a non-reinstallable package.

In #9064 we worked out a hopefully-more-clear picture of
non-reinstallability. Here we update the commentary to describe this
concept and update the lists to reflect the new definition.

Closes #9064.

Fix parsing of password-command option (#6268) (backport #9002)

Remove v2-prefix from Quickstart guide (backport #9087)

The password-command option does not parse its value correctly.
Quotes are ignored, making many kinds of commands impossible to
express (e.g.  `sh -c "foo | bar"`).  Also, `cabal user-config`
treats the argument list as a *list of option values*, rather than a
*value that is a list*.  As a consequence, `cabal user-config
update` corrupts the value in the config file.

Fix these issues by parsing the command as a space separated list of
tokens, and changing the getter to `unwords` the value and return a
*singleton* list.  Also update the argument placeholder from
`PASSWORD` to `COMMAND`.
