3966d6f16f usb_host_drv: move it to legacy_usb_host_drv
To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and
consistently name the old drivers with a legacy_ prefix.

2515196b82 lx_kit: add Platform session wrapper for x86
The x86 platform driver uses a different API than the one for ARM for
which the lx_kit glue code was designed. Since the x86 platform driver
will eventually adopt a similar interface we implement a wrapper that
encapsulates the old interface.

d7963be212 lx_emul: update to linux kernel 5.14 as default
Until now, the lx_emul layer addressed a 5.11 Linux Kernel port,
now that we add new architectures it is better to update the default version
first. There are especially changes in the task_struct code,
and the signature of some functions in the paging subsystem changed.

dc39a8db62 base: introduce Allocator::try_alloc
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.

To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.

d072c408ab dde_linux: call init_page_count for each page
The lx_emul_virt_to_pages implementation initialized the page ref
counter only for the first page, leaving the remaining elements in
uninitialized state. This, in turn, rendered the Linux page_pool (as
used by the emac network driver) ineffective, ultimately leading the a
memory leak. The fix changes the call of 'init_page_count' to take the
loop variable as argument.
