9d2e835d14 virtio-devices: Extend EpollHelper and EpollHelperHandler 
Extending and improving both the structure and the trait allows for more
flexibility regarding what can be achieved with the epoll loop. It
allows for a timeout to be configured instead of the default blocking
behavior. There is a new method in the trait to notify the caller that
the timeout has been reached. And there's a new knob to be notified with
the full list of events before the internal code will actually loop over
every event.

All of these new features are not affecting the previous behavior, and
using EpollHelper::run() should be unchanged.

a940f525a8 vmm: Move SerialBuffer to its own crate 
We want to be able to reuse the SerialBuffer from the virtio-devices
crate, particularly from the virtio-console implementation. That's why
we move the SerialBuffer definition to its own crate so that it can be
accessed from both vmm and virtio-devices crates, without creating any
cyclic dependency.

63462fd8ab vmm: serial_manager: Iterate again on EINTR 
If the epoll_wait() call returns EINTR, this only means a signal has
been delivered before any of the file descriptors registered triggered
an event or before the end of the timeout (if timeout isn't -1). For
that reason, we should simply try to listen on the epoll loop again.

0522e40933 vmm: Implement translate_gva on AArch64 
On AArch64, `translate_gva` API is not provided by KVM. We implemented
it in VMM by walking through translation tables.

Address translation is big topic, here we only focus the scenario that
happens in VMM while debugging kernel. This `translate_gva`
implementation is restricted to:
 - Exception Level 1
 - Translate high address range only (kernel space)

This implementation supports following Arm-v8a features related to
address translation:
 - FEAT_LPA
 - FEAT_LVA
 - FEAT_LPA2

The implementation supports page sizes of 4KiB, 16KiB and 64KiB.

cdcd4d259e vmm: serial: Wait for PTY to be available before writing to it 
The goal of this patch is to provide a reliable way to detect when the
other end of the PTY is connected, and therefore be able to identify
when we can write to the PTY device. This is needed because writing to
the PTY device when the other end isn't connected causes the loss of
the written bytes.

The way to detect the connection on the other end of the PTY is by
knowing the other end is disconnected at first with the presence of the
EPOLLHUP event. Later on, when the connection happens, EPOLLHUP is not
triggered anymore, and that's when we can assume it's okay to write to
the PTY main device.

It's important to note we had to ensure the file descriptor for the
other end was closed, otherwise we would have never seen the EPOLLHUP
event. And we did so by removing the "sub" field from the PtyPair
structure as it was keeping the associated File opened.

Fixes #3170
