* Implement proper GDMA allocator
* Add Kconfig option to execute ISR from IRAM on S2 and S3
Up until now, default was to execute from IRAM. This changes that for S2 and S3. ESP32 is left unchanged, because of the work that is required on it.
* maint(build): remove legacy GNU Make build system support
* maint(example): move the example so that component manager finds it
* maint(example): specify component dependency
* maint(build): clean up legacy 'register_component' usage
* maint(build): specify more fields in component manifest
* doc(readme): simplify installation instructions
See https://github.com/espressif/esp32-camera/issues/596
* maint(ci): remove tests for EOL versions (v4.1, v4.2)
* fix(build): add missing transitive dependency on driver component
* Fails with ESP32 (standard) and ESP-IDF v5.2
With IDF 5.2 master it works with esp32-s3 but fails with esp32 standard, and has two problems:
First is that when compiling it does not find the function: ets_delay_us'.
implicit declaration of function 'ets_delay_us';
Second that it fails to initialize xlock.
camera_xclk: ledc_timer_config failed, rc=103
The solution is to add #define ets_delay_us esp_rom_delay_us when the idf version is greater than 5 and initialize the variable timer_conf.deconfigure = false;

Since `gpio_install_isr_service()` is called when initializing the
camera, but on de-initiazlization the ISR service is not uninstalled.
This causes an error `gpio_install_isr_service(410): GPIO isr service
already installed` when the camera is re-initialized.

* Fix: Make esp32-camera function prototypes strict
This is required for pedantic builds with
-Wstrict-prototypes flag
* ci: Enable pedantic example build
Some camera modules come with a crystal oscillator that already provides
the main clock, and they don't have the xclk/mclk pin. We don't need to
initialize the PWM pin then.
(cherry picked from commit 896cb707dd)
* ov7670: fix ov7670_frame_control()
Last value of array (VREF) was overwritten by end marker
* OV7670: Adapt QQVGA VSTART value to remove bar on top
Remove empty bar at the top of the frame. This is more visible on
OV7675, but also present on OV7670
