Fix/improve handling of escaping in ini parser

Quoting from UPGRADING:

- A leading dollar in a quoted string can now be escaped: "\${" will now be
interpreted as a string with contents `${`.

- Backslashes in double quoted strings are now more consistently treated as
escape characters. Previously, "foo\\" followed by something other than a
newline was not considered as a teminated string. It is now interpreted as a
string with contents `foo\`. However, as an exception, the string "foo\"
followed by a newline will continue to be treated as a valid string with
contents `foo\` rather than an unterminated string. This exception exists to
support naive uses of Windows file pahts as "C:\foo\".

Closes GH-7420.

Remove 'register' type qualifier (#6980)

The compiler should be smart enough to optimize this on its own

Introduce pseudo-keyword ZEND_FALLTHROUGH

And use it instead of comments

Change Zend Stream API to use zend_string* instead of char*.

This allows to eliminate re-calculation of string lenght and hash value.

Implement 'Saner Numeric Strings' RFC:

RFC: https://wiki.php.net/rfc/saner-numeric-strings

This removes the -1 allow_error mode from is_numeric_string functions and replaces it by
a trailing boolean out argument to preserve BC in a couple of places.

Most of the changes can be resumed to "numeric" strings which emitted a E_NOTICE now emit
a E_WARNING and "numeric" strings which emitted a E_WARNING now throw a TypeError.

This mostly affects:
- String offsets
- Arithmetic operations
- Bitwise operations

Revert "Rename *.l files to *.re"

This reverts commit 969047749d33bb88a0573aa91a57e2070335111a.

Rename *.l files to *.re

This syncs PHP lexer files to all use *.re extension. The *.re files are
processed with the RE2C tool.

Implemented a faster way to access predefined TSRM resources - CG(), EG(), etc.

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.
