Better support for PICO_DISABLE_SHARED_IRQ_HANDLERS (#496)
* use PICO_DISABLE_SHARED_IRQ_HANDLERS exclusively as config for no shared handler support (rather than also PICO_MAX_SHARED_IRQ_HANDLERS == 0)
additionally make irq_add_shared_irq_handler() call irq_set_exclusive_handler() so that single usage of an IRQ still works

* Comment typo

Small API additions and minor fixes (#406)
* Add missing DREQ_s

* store actual clock frequency in clock_configure (fixes #368)

* use dma DREQ values defined in dreqs/dma.h

* Fix hw_is_claimed, and add xxx_is_claimed APIs

* Add some PIO irq helper methods

* Add DMA channel IRQ status getter and clear methods

* Implement the correct PIO IRQ status/clear methods (good to have methods here as the h/w interrupt registers are super confusing)

* fix pico_multicore dependencies

* add missing wrapper func __aeabi_f2d

* Further DMA/PIO IRQ API cleanup (and review fixes)

* add PICO_INT64_OPS_IN_RAM flag

Fixup divider save_restore for floating point too; improve tests (#405)
- The divider state needs to be saved for __aeabi_ddiv, __aeabi_fdiv, __aeabi_dtan and __aeabi_ftan or they won't work in interrupts *(probably not used much youd hope), or on an RTOS context switch
 - Refactored code out for the integer and floating point cases
 - Improved the floating point 'tests' in passing to check more return values against GCC implementations
 - Added floating point usage to the IRQ nesting test case

Don't advertise REMOTE_WAKEUP for USB stdio as it is is not currently implemented. Longer term need to implement REMOTE_WAKUP properly in TinyUSB.

e9a521a9b1 rtc_get_datetime: read the rtc registers just once each
In order for the returned value to accurately reflect a single moment in time,
ensure the registers are read just once and in the datasheet order.
Before this change, the RTC registers would each be read multiple times,
leading (infrequently) to the returned fields not all reflecting the same
moment in time.

The rp2040 datasheet has what I believe is an incorrect example (embedding
the source of this function); will the datasheet be updated if this function is
fixed?

This problem is only a speculative one; I did not actually observe it in the
wild.
