Add support for face customization
Allows customization of faces using customize-set-faces. This makes it
easier to manage customization in version control. Instead of having all the
faces written in a custom.el, the faces can be customized where the rest
of the package is configured.

Allow `:diminish` with no arguments
When given no arguments, have :diminish assume it should diminish a
mode named after the current package (the package’s name, with “-mode”
appended, if it’s not already) to an empty string.
When given only a string to diminish an implicit package name to, do
not append “-mode” to the package name if it already ends with
it. (This is a backwards-incompatible change if someone was
diminishing a package named “foo-mode” implementing `foo-mode-mode`.)
Add test cases for `use-package-normalize-diminish`.
This addresses some of the redundancy mentioned in issue https://github.com/jwiegley/use-package/issues/288.

Fix bug in use-package-install-deferred-package
Previously, deferred installation didn't work because I didn't convert
the result of a `completing-read' back from a string to a symbol,
which meant the hash-table lookup failed.

Add `:magic` and `:magic-fallback` keywords (issue)
These keywords work equivalently to `:mode` or `:interpreter`, but for
`magic-mode-alist` and `magic-fallback-mode-alist`.
The handler function implementation is now passed a list to add to,
and shared by all four of them.

Protect against errors during package install
If the network is missing and there is a new use-package with :ensure,
startup would fail part of the way through due package.el being unable
to reach the package repo. This will catch that error and report it
while allowing startup to continue.
Make use-package-normalize-value handle nil better
The previous version of `use-package-normalize-value', when passed
nil, would return the list (symbol-value (quote nil)). This meant that
keywords which used `use-package-normalize-value' or the higher-level
normalizer `use-package-normalize-test' would get a non-nil
argument (i.e. the above list) even when the user specified nil to the
package.
This had the concrete impact of making it so that :defer-install nil
was treated as :defer-install t.
The parsing logic in `use-package-normalize-pairs' is not designed to
deal with keyword arguments. However, `use-package-normalize-pairs' is
used to process the arguments to :bind, which can include keyword
arguments. These keyword arguments are supposed to be passed untouched
to the underlying `bind-keys' function, but there is a clause in
`use-package-normalize-pairs' that replaces lists with their first
element. Thus an invocation like:
(use-package company
:bind (:map company-active-map
:filter (company-explicit-action-p)
("RET" . company-complete-selection)))
Which generates an error since `company-explicit-action-p' is now
being referenced as a variable rather than a function.
The proper solution is to refactor the logic that goes into parsing
uses of :bind, but this commit adds a temporary patch to eliminate the
above problem, while trying to be as reverse-compatible as possible.
In particular it just inhibits the list-to-first-element
transformation when the previous element processed was a keyword.
* A quoting error has been fixed in `use-package-handler/:defer'.
* `use-package-install-deferred-package' has been updated to return t
if the package was actually installed, and nil otherwise.
* The fake autoloads generated during deferred installation are
doctored so Emacs does not think they were defined in the user's
init-file.
* The docstrings of the fake autoloads have been improved.
* Arguments and interactivity are now correctly passed to the
autoloaded function.
* The autoload now skips requiring the feature and calling the
original function if the user declines to install the package. This
prevents unprofessional errors.
This time around, I've gotten rid of the advice on `require' (that was
never going to work) and instead made `use-package' try to handle
loading the package at the appropriate time. In particular, when
deferred installation is active, all the autoloads generated by
`use-package' are not regular autoloads, but regular functions that
will install the relevant package, require the relevant feature, and
only then call the newly defined (autoloaded) function.
Some smarter logic has been added to make sure things like `:demand'
play nicely with the autoloading system; see the extensive comment in
`use-package-handler/:defer-install' for more information on how that
works.
There was a section in `use-package-install-deferred-package' which
referred to a nonexistent variable `use-package--deferred-features';
that has been removed.
There is now, in addition to `use-package-ensure-function', a new
variable called `use-package-pre-ensure-function'. This is intended
for use by package managers which, unlike package.el, activate
autoloads package-by-package instead of all at once. Even if a package
is marked for deferred installation, the user would likely want its
autoloads activated immediately *if* it was already installed. The
logic for doing that can now be put in
`use-package-pre-ensure-function'.
This new keyword, if provided along with a non-nil value, causes the
action of :ensure to be deferred until "necessary". Package
installation can be triggered by the user calling the new interactive
function `use-package-install-deferred-package', or by the feature
declared by the `use-package' form being required. This latter
behavior seems to be the simplest way to make sure that package
installation actually takes place when it needs to, but it requires
that an advice be added to `require', which may be considered overly
intrusive. (Also, it's generally considered bad practice for functions
in Emacs to put advice on other functions in Emacs.) Thus it may make
sense to add an option or function to explicitly enable this behavior,
if there does not turn out to be a better way to accomplish deferred
installation.
Documentation has not been updated to reflect :defer-install yet.
Extend capabilities of use-package-ensure-function
Modify the expected API of `use-package-ensure-function' so that it is
passed three arguments: the name of the package declared in the
`use-package' form; the argument passed to `:ensure'; and the current
`state' plist created by previous handlers. (Previously, it was only
given a single argument, which was the argument passed to `:ensure',
or the name of the package declared in the `use-package' form, if the
former was `t'.
This allows for more flexibility in the capabilities of the
`use-package-ensure-function' implementation. For example, its
behavior can change depending on the values of other keywords, if
those keywords modify the `state' plist appropriately.
