When bash-completion (and thus `_known_hosts_real()`) is / is not available this
will typically not change during the lifetime of a shell.
The only exception is if the user would unset `_known_hosts_real()`, but well,
that would be his problem.
So we can easily define `__fzf_list_hosts()` either using `_known_hosts_real()`
or using the old code, and avoid checking every time whether
`_known_hosts_real()` is defined.

If defined, use bash-completions’s `_known_hosts_real()`-function to create the
list of hostnames.
This obviously requires bash-completion to be sourced before fzf.
If not defined, fall back to the previous code.

Just like it’s already done for `_fzf_compgen_path()` and `_fzf_compgen_dir()`
allow a user to easily define his own version of `__fzf_list_hosts()`.
Also add some documentation on the expected “interface” of such custom function.

`__fzf_list_hosts()` seems like a function a user may want to override with some
custom code.
For that reason it should be kept as simple as possible, that is printing only
hostnames, one per line, optionally in some sorting.
The handling of adding a `username@` (which is then the same for each line), if
any, would unnecessarily complicate that for people who want to override the
function.
Therefore this commit moves that to the places where it's actually used (as of
now only `_fzf_complete_ssh()`).
This also saves any such handling for `_fzf_host_completion()`, where this isn’t
needed at all.
Right now it comes at a cost, namely an extra invocation of `awk` in the
`_fzf_complete_ssh()`-case.
However, it should be easily possible to improve `__fzf_list_hosts()` to no
longer need the final `awk` in the pipeline there.

This commit causes all simple commands that are not built-ins or functions to be
invoked via `command` in order to protect them from alias substitution or from
accidentally taking functions of the same name.
It was decided to not “protect” `fzf` and `fzf-tmux` for now.
Maybe a better solution should be implemented for that in the future.

* [bash] bring fzf’s own bash completion up to date
This orders and groups completed options and values in just as they appear in
the code respectively, for some option values, as they’d be printed in the
`--help`-output.
It does not add support for completion of `:` right after values that support an
optional `:some-further-value` postfix.
Neither does it add support for the `--option=value`-style.

* [bash] drop unnecessary code in handling `history`
Presumably, the dropped code is not needed for any effect, thus drop it.

* [bash] return instead of not executing an if-block, when non-interactive
This should keep the code more readable, be less error prone (accidentally doing
something outside the if-block and aligns the code with what’s already done for
zsh.
`0` is returned, because it shall not be considered an error when the script is
(accidentally) sourced from a non-interactive shell.
If executed as a script (rather than sourced), the results are not specified by
POSIX but depend on the shell, with bash giving an error in that case.

* [shell] exit immediately when called from non-interactive shell
The shell execution environment shouldn’t be modified at all, when called from a
non-interactive shell.
It shall be noted that the current check may become error prone for bash, namely
in case there should ever be a differentiation between `i` and `I` in the
special variable `-` and bash’s `nocasematch`-shell-option be used.

When just checking whether a function is already defined or not, it’s not
necessary to print out it’s definition (should it be defined).
bash’s `declare` provides the `-F`-option (which implies `-f`), which should
give a minor performance improvement

`find`’s `-path`-option is described to use shell patterns (i.e. POSIX’ pattern
matching notation).
In that, `.` is not a special character, thus escaping it shouldn’t be
necessary.
