This reverts commit eb6649e0c2.

Previously, pointers were associated with the function identifier, now they're associated with the return type

This resolves conflicts with declarations that can be interpreted as binary_expressions

* feat: allow identifiers in string concatenations

Resolves errors in strings of the form:

   ("failed in line %" PRIdLINENR)

_Generic is a C11 feature, __restrict__ and _Noreturn were added to type_qualifiers

It's allowed in gcc and clang

According to cppreference, identifiers are `(XID_Start | '_')
XID_Continue*`, which is the case as of C++23 and C2x. I have confirmed
this myself with the drafts of C++23 and C2x.

https://en.cppreference.com/w/cpp/language/identifiers

Clang indeed implements identifiers as `(XID_Start | '_') XID_Continue*`
in C++ mode and C2x mode, with a slight extension to the character set
to include some extra math characters:
231992d9b8/clang/lib/Lex/Lexer.cpp (L1517-L1530)

This also lets it bind to _any_ statement, which is necessary for some
c++ attributes that can attach to the statement in if, while, and
do/while statements.

* Add support for C23 attributes

https://en.cppreference.com/w/c/language/attributes

* Use wrapper for statements with attributes to reduce state machine size

* Missed a couple _declarators that needed attributes directly after

* Use annotated_declarator for declarators that have attributes immediately following them

* Give field and type declarators the same attribute treatment

* Add support for Microsoft-specific modifiers

Microsoft-specific modifiers are keywords can be used to modify declarators to form derived types.

The specification for the modifiers themselves is here:
https://docs.microsoft.com/en-us/cpp/cpp/microsoft-specific-modifiers?view=vs-2019

* 0.16.1

* Add a rule for left part of assignment: it'll be helpful to add scoped_name_identifier (c++)

* Inline the assignment_left_expression rule

* #include can be followed by a macro name or a macro call

* In preproc_include, use preproc_call_expression

* Parse expressions in preprocessor #if statement

* Make preproc_expression look like a normal expression

* Hide the wrapper rules
* Alias the rulres to match their corresponding expression rule
* Handle line continuations as extra tokens

Fixes #32

Fixes #31

* Fix multi-statements in for initializer and update parts

* Finally the bug was only in the initializer part

* Fix error with ++L (consequence of support for L strings)

* Update to tree-sitter 0.15.5

Fixes #24

* Handle __attribute__ in function declaration

* Fix tests in examples/

* Remove useless optional
