When we encounter an invalid unicode escape within a regular
expression, we now pass that error on to Onigmo as if it didn't
exist in the parser (which matches the upstream parser's behavior).
We do this because there are tests that specify that you are
allowed to have invalid Unicode escapes if they are within the
context of a regular expression comment for a regular expression
in extended mode. That looks like:
/# \u /x
Note that this _only_ applies to Unicode escapes (as opposed to
applying to hex or meta/control escapes as well). Importantly it
also only applies if the regular expression is terminated. An
unterminated regular expression will still get error handling done
in the parser. That would look like:
/# \u
that would result in the same error handling we have today.

Add the ability to receive a callback when the parser encounters a
shebang that contains additional switches after the Ruby engine.
This is necessary because some command-line flags may be present
there that will alter the parse.

`Prism.lex` and `Prism.lex_file` return `ParseLexResult` instead of `Array`.
`Prism::parse_lex` and `Prism::parse_lex_file` return `ParseLexResult` instead of `ParseResult`.
This PR updates the documentation to reflect these return values.

memory-mapped files
> ..., and on other POSIX systems we'll use `read`.
As `pm_string_mapped_init`'s doc comment says, it should fall back to
`read(2)`-based implementation on platforms without memory-mapped files
like WASI, but it didn't. This commit fixes it by calling `pm_string_file_init`
in the fallback case.
Also `defined(_POSIX_MAPPED_FILES)` check for `read(2)`-based path is
unnecessary, and it prevents the fallback from being executed, so this
change removes it.

PRISM_SERIALIZE_ONLY_SEMANTICS_FIELDS is set

This PR tweaked the documentation to correct an error encountered
when running the example code of `Prism::Dispatcher`.
This aims to make understanding the example smoother.

prefixed values
This commit prevents the following unary operators from being accepted
as the value prefix of a block's optional parameter:
- `+`
- `-`
- `~`
- `!`
For example, `f { |a = +b| }` will now raise a syntax error.

ruby/ruby measures test coverage of C code, but the `#line` directive
generated by prism points to a file that does not exist, so coverage is
not taken properly.
This changeset specifies the location of the source files as a relative
path in terms of ruby/ruby repo.

When an implicit array is used in a write, is causes the whole
expression to become a statement. For example:
```ruby
a = *b
a = 1, 2, 3
```
Even though these expressions are exactly equivalent to their
explicit array counterparts:
```ruby
a = [*b]
a = [1, 2, 3]
```
As such, these expressions cannot be joined with other expressions
by operators or modifiers except if, unless, while, until, or
rescue.
