strip_last_element at Path removes everything after the trailing slash,
which causes lookup failures at the VFS server when opening directories.
Issue #1648
Throw Invalid_name, No_space, and Out_of_node_handles where appropriate.
Catch the new range of errors thrown by at the VFS.
Catch Out_of_node_handles at the VFS, but print a message and re-throw.
Issue #1648
This patch introduces a shortcut for conditional session routes of the
form '<if-arg key="label" value="..."/>'. With this change, the label
can be directly specified as 'label' attribute of an '<any-service>' or
a '<service>' node. The '<if-arg>' mechanism was not documented anyway
and I hope to be able to ultimately remove it.
Don't skip the cleanup call if a pager object is marked as blocked.
It happens that the pager_object is in destruction but it is also used
concurrently by the pager thread. The pager thread handling code may set the
pager object to blocked but still uses the pointer to the pager object. Avoid
locking at the state of the pager object and make the cleanup call everytime.
Error output looks like this, where the pf_ip is within
void Pager_object::_page_fault_handler(addr_t pager_obj)
method and the pf_addr is the stale pointer to the already released pager_object.

Currently, when a signal arrives in the main thread, the signal dispatcher is
retrieved and called from the main thread, the dispatcher uses a proxy object
that in turn sends an RPC to the entry point. This becomes a problem when the
entry point destroys the dispatcher object, before the dispatch function has
been called by the main thread. Therefore, the main thread should simply send an
RPC to the entry point upon signal arrival and the dispatching should be handled
solely by the entry point.

* handle interrupts depending on mode of operation
* spelling fixes
* move ATA 'Idendity' struct to ata header

- 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.
Too less memory quota for a PD may be calculated, which leads to too early
punishment for a Genode process.
Discovered during Turmvilla scenario #1552 and issue #1733.
Additionally print warnings about unavailable CPUs if they are tried to be
used during pager object setup.

threads with prio 0 will not be started and would fail silently.
Happened on Turmvilla for the USBProxy thread in virtualbox.
Discovered during Turmvilla scenario #1552 and issue #1733.
Reduces kernel log message noise when running on kernel-debug branch.
Additionally add a more verbose core message.
Discovered during Turmvilla scenario #1552 and issue #1733.
Under some circumstances, the diagnostic message in the exception signal
handler was not printed. This could happen due to a dead lock in the
console library if the console code itself produces the exception while
possessing the mutex, e.g., by exhausting a undersized stack. Now, we
directly write to the log session via the stdout_write() hook or use
raw_write_str() in core.
