Summary: I came across an outstanding FIXME to make the format style customizable. Inspired by the include fixer, I added an new option `-style` to configure the fallback style in case no clang-format configuration file is found. The default remains "llvm".

General overhaul to fix many coding bugs, simplify the code, and improve readability.
* Clarify documentation strings of user options.
* Say that clang-include-fixer-executable is a file to have auto completion.
* Allow user to select available options for clang-include-fixer-input-format. Turn it into a symbol as it's not a free-form string.
* Remove clang-include-fixer-query-mode. This option was apparently used to select between two different operation modes, which is not a typical use case for user options. Provide two separate commands instead.
* Add a face for the overlay highlighting so that users can customize it.
Move user commands to the front so that readers of the code aren't buried in internal functions.
* Make process calls asynchronous. This is possible here because clang-include-fixer doesn't change files in place. This means input is no longer blocked while clang-include-fixer is running.
* Factor out logic in helper functions to keep functions short.
* Add comments where appropriate.
* Provide an alternative buffer replacement strategy for the case that a single line was inserted (the normal case in the case of clang-include-fixer). This keeps point, markers, and other buffer information intact.
* Use let-alist and association lists instead of property lists to shorten the code.
* Instead of highlighting only the first occurrence of a symbol, highlight all occurrences and move point to the closest one.
* Detect qualified names at point.
* Use filepos-to-bufferpos if available.
* Formatting.
Patch by Philipp Stephani!
llvm-svn: 283306
Having both rename-at and rename-all both seems confusing and introduces
unneeded difficulties. After merging rename-at and rename-all maintaining main
function wrappers and custom help becomes redundant while CLI becomes less
confusing.
D24224 (which was the original patch causing buildbot failures) wasn't aware of
bugs caused by passing both -offset and -qualified-name. After D24224 was landed
it caused buildbot failures and therefor I just reverted it.
Two things that make this patch different from D24224 are:
* unittests/clang-rename was deleted, because it is unmaintained and doesn't do
much.
* Passing both `-offset` and `-qualified-name` isn't allowed anymore for the
sake of preventing bugs.
This patch is a trivial enhancement of accepted D24224 revision.
Tested with `ninja check-all`.

Having both rename-at and rename-all both seems confusing and introduces
unneeded difficulties. Allowing to use both -qualified-name and -offset at once
while performing efficient renamings seems like a feature, too. Maintaining main
function wrappers and custom help becomes redundant while CLI becomes less
confusing.

intervening reinitialization.

This patch extends readability-container-size-empty check allowing it to produce
warnings not only for STL containers, but also for containers, which provide two
functions matching following signatures:
* `size_type size() const;`
* `bool empty() const;`
Where `size_type` can be any kind of integer type.
This functionality was proposed in https://llvm.org/bugs/show_bug.cgi?id=26823

llvm-svn: 280180
Summary:
The check emits a warning if std::move() is applied to a forwarding reference, i.e. an rvalue reference of a function template argument type.
If a developer is unaware of the special rules for template argument deduction on forwarding references, it will seem reasonable to apply std::move() to the forwarding reference, in the same way that this would be done for a "normal" rvalue reference.
This has a consequence that is usually unwanted and possibly surprising: If the function that takes the forwarding reference as its parameter is called with an lvalue, that lvalue will be moved from (and hence placed into an indeterminate state) even though no std::move() was applied to the lvalue at the callsite.
As a fix, the check will suggest replacing the std::move() with a std::forward().
This patch requires D23004 to be submitted before it.
