Josef Söntgen 9606abc146 dde_ipxe: remove dde_kit
A long long time ago, in a galaxy^W^W^W we used DDE kit to ease the
porting of purely C based drivers. By now it became clear, that we
do not gain that much by following this approach. DDE kit contains
much generic functionality, which is not used or rather not needed
by most ported drivers. Hence, we implement a slim C wrapper on top
of Genode's C++ APIs, that is especially tailored to the driver.

In addition to removing the dependency on DDE kit, the iPXE driver
now uses the server framework and the newly introduced signal based
IRQ handling.

Issue #1456.

Josef Söntgen 09e96dfdcd dde_kit: use async IRQ session interface
Up to now, dde_kit used the synchronous IRQ session interface. This

Stefan Kalkowski b32af4e0a4 hw: directly reference kernel objects from core

Stefan Kalkowski c850462f43 hw: replace kernel's object id allocators
Instead of having an ID allocator per object class use one global allocator for

superfluent. Moreover, replace the base-hw specific id allocator implementation
with the generic Bit_allocator, which is also memory saving.

Christian Prochaska 63ebebcfa4 nitpicker: update the 'pointed session' more often
Currently, the 'pointed session' gets updated only when an input event
occurs, but an update is also needed in other situations, for example
when the view under the current mouse position was moved.

With this commit, the 'pointed session' gets updated whenever the
timer-triggered 'handle_input()' function is called.

Christian Prochaska 0fd53c7fe4 Extract numeric string arguments with the correct signedness
There are lots of places where a numeric argument of an argument string
gets extraced as signed long value and then assigned to an unsigned long
variable. If the value in the string was negative, it would not be
detected as invalid (and replaced by the default value), but become a
positive bogus value.

With this patch, numeric values which are supposed to be unsigned get
extracted with the 'ulong_value()' function, which returns the default
value for negative numbers.

Norman Feske ea9c2199e8 base: extend emergency dataspace size
The emergency dataspace is used to accommodate the corner case where
a signal context capability is created while issuing the first
resource request. Normally, the attempt to upgrade the signal-session
quota under such a constrained situation would fail. By freeing the
emergency dataspace in this situation, we regain enough quota to
upgrade the signal session.

This is a follow up commit for "base: Raise RAM quota of signal session
to 16K" and fixes the resource_request test on 64-bit platforms.

* Improves robustness of the parsing of function arguments by
  considering nameless arguments in function declarations, default
  values, varargs.
* Consider const qualfiers in return types.
* Added support for the override, constexpr keywords.
* Parsing of overloaded operators.
* Improved handling of type definitions.
* Added parsing of template arguments.
* Handling of template constructors.

Reto Buerki c82f5e9269 hw_x86_64: Do not mask edge-triggered interrupts
Do not mask edge-triggered interrupts to avoid losing them while masked,
see Intel 82093AA I/O Advanced Programmable Interrupt Controller
(IOAPIC) specification, section 3.4.2, "Interrupt Mask":

"When this bit is 1, the interrupt signal is masked. Edge-sensitive
interrupts signaled on a masked interrupt pin are ignored (i.e., not
delivered or held pending)"

Or to quote Linus Torvalds on the subject:

"Now, edge-triggered interrupts are a _lot_ harder to mask, because the
Intel APIC is an unbelievable piece of sh*t, and has the edge-detect
logic _before_ the mask logic, so if a edge happens _while_ the device
is masked, you'll never ever see the edge ever again (unmasking will not
cause a new edge, so you simply lost the interrupt)."

So when you "mask" an edge-triggered IRQ, you can't really mask it at
all, because if you did that, you'd lose it forever if the IRQ comes in
while you masked it. Instead, we're supposed to leave it active, and set
a flag, and IF the IRQ comes in, we just remember it, and mask it at
that point instead, and then on unmasking, we have to replay it by
sending a self-IPI." [1]
