0d0ebd5a7f libports: lwip change SOL_SOCKET definition
Our FreeBSD libc based libc defines SOL_SOCKET as 0xffff. We change
lwip's definition from 0xfff to match ours. This prevents us from
converting the level when we call {g,s}etsockopt.

Fixes #292.

ab951175c0 libports: fix openssl issues and update to 1.0.1c
libcrypto provides certain optimized assembler functions which
unfortunatly are non-pic. Therefore this asm code is removed
and libcrypto is build with -DOPENSSL_NO_ASM.
Because the asm code is not needed anymore, its generation is
also removed from openssl.mk.

import-libssl.mk was also added because it is essential for building
programs which depend on libssl.

Fixes #291.
Fixes #294.

d28465cb3a Noux: fix missing mode propagation
When opening a new file, a new Fs_vfs_handle is created but with the
initial mode set to 0 which is not expected by functions like fdopen()
that check if the original flags given to the open() call match the
returned ones on the used fd.

Fixes #289.

b50970fb74 USB: Test and fix errors on x86 boxes
Added support for more than one UHCI controller. Make sure the 'PIRQ' bit in the
legacy support register (PCI config space) of the UHCI controller is enabled and
also that the 'Trap on IRQ' bit is disabled. Fix offset bug in PCI-config space
emulation for Linux.

e1435a3f57 Replace old test/block with test/ahci
The block test at test/ahci is indeed not AHCI-specific. It is a generic
block read/write test for the block-session interface. But in contrast
to the original test/block, it restores the block device content (at
least when the test succeeds). Hence, we remove the original (dangerous)
block test and always use code of test/ahci.

4ece3b3c77 Deadlock fix in rm_session on NOVA platform
Rm_client is derived from Pager_object. If the Pager_object is also
derived from Thread_base (which is the case for NOVA) then the
Rm_client object must be destructed without holding the rm_session_object
lock. The native platform specific Thread_base implementation has to take
care that all in-flight page handling requests are finished before
destruction. On NOVA it is done by doing an IPC to the pager thread.
(performed in Pager_object::dissolve() in base-nova). The
called thread than executes its operation until end which also requires
in some cases to take the rm_session_object lock.

Since _client_slab insertion/deletion also must be performed
synchronized but can't be protected by the rm_session_object lock
because of the described dead_lock situation, we have
to use a synchronized allocator object to perform insertion and
deletion of Rm_clients.

f8c97e7189 NOVA: Deadlock fix in pager/rm_session interaction
Following deadlock happens when a Rm_client/Pager_object handles a page-fault
and concurrently the same object is dissolved (triggered by parent killing
the client).

The situation is as follows:

Page fault handling  :
base-nova/src/base/pager/pager.cc    : pf_handler() - lock pf_lock
base/.../core/rm_session_component.cc: pager()      - lock rm_session
  (in reverse_lookup())

Dissolve of Rm_client:
base/src/core/rm_session_component.cc: dissolve()   - lock rm_session
base-nova/src/base/pager/pager.cc    : dissolve()   - lock pf_lock

The pf_lock is not required here during normal page fault handling,
since this pager object @NOVA is executed only by one and the same
thread and all critical operations inside the rm_session_object itself
are locked anyway. The only critical point is the destruction of the
Pager_object which is already handled in the both dissolve functions
of the rm-session_component (locking) and the pager_object (finalize
in-flight page faults).

1d6a00f01a Cleanup: cap allocation
Allocate exc_pt_sel inside Thread_base object
instead of pager object, since it is a thread
specific characteristic.

Same for freeing of the thread capabilities:
- ec, sc, rs, exc_pt_sel is thread specific
and has nothing to do in server nor pager object.

1a94c3b623 Fix: thread identifier comparator
The invalid thread is specified as 0,0,-1 (ec cap, sc cap, sem cap).
The main thread is specified as 0,0,0.

The comparator identified "tid_main == tid_invalid" as equal,
which is obviously wrong.

The patch compares at least ec and sem cap.
