Some structs, specically CPUARMState is 16-bytes aligned.
This causes segment fault because gcc tends to vectorize
the assignment of the struct with infamous movaps tricks.
Without this patch, we fail on manylinux with 2.17 glibc
in release mode in i686.
qemu_memalign will ensure the alignment across platforms.
* optimize ram block handling
Save the last element of the ram_list. This allows to
faster find where to add new elements when they are not
bigger then page size.
* save ram_list freed
this keeps the optimization for find_ram_offset() intact after snapshot
restore.
* cow only clear the tlb of affected pages
* update flatview when possible
Building each flatview new when the memory has changed is quite
expensive when many MemoryRegions are used. This is an issue when using
snapshots.
* update benchmark for new api
* save flatview in context
this avoids rebuilding the flatview when restore a context.
* init context flatview with zero
* address_space_dispatch_clear remove subpage with higher priority
* docutemnt the options for UC_CTL_CONTEXT_MODE
Specialy stress that with UC_CTL_CONTEXT_MEMORY it is not possible to
use the context with a different unicorn object.
* Styling and commets fixes
* Add errno API support
* Improve OOP approach by adjusting the way reg types are selected
* Leverage new approach to deduplicate reg_read and reg_write code
* Adjust reg_read_batch
* Add support for reg_write_batch
* Adjust x86 MSR accessors
* Turn asserts into descriptive exceptions
* Improve comments and styling
* Fix ARM memcpy neon regression test
* Modify canonicals import
* Introduce ARM CP reg accessors
