This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

The zend_signals_activate() function is called in php_request_startup()
even if `--disable-zend-signals` is used. This causes uninitialized
variables to be used on ZTS builds.
This was removed in 7.1 in c870633. Removing guards from the SAPIs
should be fine, but removing the guard from main/main.c prevents anyone
using the static embedded library to integrate PHP into their programs.

Make sure the hash entry is an array.
The origin fix broke support for HOST/PATH ini sections. Only the
beginning of the string has to match. Revert this check but use
zend_binary_strncasecmp instead of strncasecmp.
Per unix(7):
abstract: an abstract socket address is distinguished (from a
pathname socket) by the fact that sun_path[0] is a null byte
('\0'). The socket's address in this namespace is given by the
additional bytes in sun_path that are covered by the specified
length of the address structure. (Null bytes in the name have no
special significance.) The name has no connection with filesystem
pathnames. When the address of an abstract socket is returned,
the returned addrlen is greater than sizeof(sa_family_t) (i.e.,
greater than 2), and the name of the socket is contained in the
first (addrlen - sizeof(sa_family_t)) bytes of sun_path.
The existing implementation was assuming significance in null bytes
contained in the abstract address identifier.
