The upgrade for #11002 (closed)

Upgrade of PHP to 7.4 and rebuild of php extensions for it

• supersedes !1808 (closed)
• upgrade for extensions rebased from !9179 (closed) where tests for dependent ones were tested
• some work for linting using !9194 (closed)

Ref https://www.php.net/manual/en/migration74.php

Current state https://github.com/php/php-src/blob/PHP-7.4/UPGRADING

• removed extensions (recode & wddx) https://www.php.net/manual/en/migration74.removed-extensions.php
• onigmura has been unbundled in https://github.com/php/php-src/commit/d1c1481081ef6280bf403b290501ca62d736cb8b
• added TRAVIS=true SKIP_IO_CAPTURE_TESTS=1 because tests now rely on this variables to skip risky tests
• added -D_LARGEFILE_SOURCE and -D_FILE_OFFSET_BITS=64 as recommended https://www.php.net/manual/en/intro.filesystem.php
• lots of tests now pass but few new ones added and sorted (echant2 compatibility could be backported as patches from master)

List of failed tests updated from https://code.foxkit.us/adelie/packages/-/blob/master/user/php7/disabled-tests.list
