Instead of just red messages in the log and a hanging caller, the issuer
may respond to it - e.g. a noux bash shell will show an error and is
afterwards still usable.

Instructions:
1. Create a file in terminal one in the 'ram' directory
! echo "test" > ram/test
2. Second terminal
! tail -f ram/test
3. First terminal
! echo "Meaningless output" >> ram/test
4. Observe second terminal
Trapping rdtsc creates a huge load in some guests, e.g. Windows 8.1,
that use this instruction very frequently. This influences audio
playback/recording in a bad way (distorted sounds, …). As a interim
solution disable the virtualization of rdtsc completely. As long
as each guest VM runs on its own CPU core it should be fine as there
should not be that much interference (TSC warping).
That being said, TSC offsetting as well as adjusting within vbox have to
be evaluated.

- we claim to have no limits on file handles and number of threads
- remove obsolete Thread_base::myself fall-back code for stack size calculation
Issue #1733.
Defer destruction of threads which tries to self-destruct. Check an perform
cleanup of such threads during pthread_cancel and pthread_create.
Issue #1687
Instead of white-listing floppy controllers, certain SCSI controllers
as well as ISAPnP etc. pp. remove the diagnostics and print each access
if verbose is set.
Fixes#1726.
Instead of using the alarm_timer thread we use our own timer thread
that uses a kernel semaphore on Nova. On all other platforms a timer
connection and trigger_once is used.
Fixes#1727.
* Move the Synced_interface from os -> base
* Align the naming of "synchronized" helpers to "Synced_*"
* Move Synced_range_allocator to core's private headers
* Remove the raw() and lock() members from Synced_allocator and
Synced_range_allocator, and re-use the Synced_interface for them
* Make core's Mapped_mem_allocator a friend class of Synced_range_allocator
to enable the needed "unsafe" access of its physical and virtual allocators
Fix#1697
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
Instead of returning pointers to locked objects via a lookup function,
the new object pool implementation restricts object access to
functors resp. lambda expressions that are applied to the objects
within the pool itself.
Fix#884Fix#1658
If the guest is not in an interruptible state when the recall handler is
called, an assertion fails. Since the assertion is only relevant if the
recall handler was called during IRQ injection, it should be moved into
the corresponding conditional block which already has the assertion for
the 'IF' flag.
Fixes#1661
