PDO MySQL: Use native types for results

Previously, PDO MySQL only fetched data as native int/float if
native prepared statements were used. This patch updates PDO to
have the same behavior for emulated prepared statements, and thus
removes the largest remaining discrepancy between these two modes.

Note that PDO already has a ATTR_STRINGIFY_FETCHES option to control
whether native types are desired or not. The previous output can
be restored by enabling this option.

Most of the tests make use of that option, because this allows the
tests to work under libmysqlclient as well, which currently always
returns string results (independently of whether native or emulated
PS are used).

Another pass making some failure states unconditional erros in PDO

Also make internal function return type more accurate to inform usage

Make various failure conditions in PDO unconditional errors

This includes TypeErrors, ValueErrors, Error for uninitialized objects
and invalid user classes/callable instanciation

Use variadic signature for PDOStatement::fetchAll()

The current signature is incorrect, because the $ctor_args parameter
is not required to be an array (it can at least also be null, and
isn't enforced by an exception anyway).

I'm going for the variadic signature here, because we already use
the same variadic signature in PDO::query() and
PDOStatement::setFetchMode(), all of them accepting essentially the
same arguments.

Sync leading and final newlines in *.phpt sections

This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines in all
*.phpt sections.

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.

Remove more PHP 6 leftovers from tests

Tweak uncaught exception message display

This implements a reduced variant of #1226 with just the following
change:

-Fatal error: Uncaught exception 'EngineException' with message 'Call to private method foo::bar() from context ''' in %s:%d
+Fatal error: Uncaught EngineException: Call to private method foo::bar() from context '' in %s:%d

The '' wrapper around messages is very weird if the exception
message itself contains ''. Futhermore having the message wrapped
in '' doesn't work for the "and defined" suffix of
TypeExceptions.

Display EngineExceptions like ordinary exceptions

TypeException stays as-is for now because it uses messages that are
incompatible with the way exception messages are displayed.

TypeException stays as-is for now because it uses messages that are

closure_038.phpt and a few others now show that we're generating
too many exceptions for compound operations on undefined properties
-- this needs to be fixed in a followup.
