Use libavifinfo's AvifInfoGetFeaturesStream() in php_handle_avif() to
get the width, height, bit depth and channel count from an AVIF
payload. Implement stream reading/skipping functions and data struct.
Use libavifinfo's AvifInfoIdentifyStream() in php_is_image_avif().
Update the expected features read from "test1pix.avif" in
getimagesize.phpt.
Closes GH-7711.
Most bundled libraries in PHP code already include license information
in the dedicated README.REDIST.BINS file. Instead of complicating
documentation files more this patch only updates the PCRE license info
in the readme file.
Changes to simplify managing libgd docs a bit:
- Move copyright statement and licensing info to common redistributable
bins file. All previous notices left intact and updated with the
upstream info.
- Remove unsynced and difficult to track README file compared to
upstream README.md file available at https://github.com/libgd/libgd
- More common filename accross the PHP repository
- Additionally, this patch replaces some legacy form feed (FF or ^L)
characters (for printers) to LF (\n) newline character.
Since there is no need to patch libsqlite3 for our purposes, and since
libsqlite3 ≥ 3.3.9 (which is our current requirement) is widely
available on distros, there is no reason anymore to bundle the library.
Besides removing the bundled libsqlite, and adapting the configuration
respectively, we also fix the use of the SQLITE_ENABLE_COLUMN_METADATA
compile time constant to detect whether sqlite3_column_table_name() is
available by a working feature detection (otherwise bug_42589.phpt
would fail). We also skip bug73068.phpt for libsqlite 3.11.0 to
3.14.1 which have a bug (<https://sqlite.org/src/info/ef360601>).
We also completely drop support for the obscure pdo_sqlite_external
extension (which could have been enabled on Windows only by passing
`--pdo-sqlite-external` to configure), since it is not needed anymore.
Furthermore, we remove references to the bundled libsqlite from
Makefile.gcov, CONTRIBUTING.md and README.REDIST.BINS.
