a528aa097a init: add 'label' criterion for session routing
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.

ceb04d3c11 nova: avoid race in pager_object destruction
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.

no RM attachment (READ pf_addr=xxx pf_ip=xxx from 00 <NULL>)
static void Genode::Pager_object::_page_fault_handler(Genode::addr_t): page fault, thread '<NULL>', cpu x, ip=xxx, fault address=xxx

PAGE-FAULT IN CORE (READ pf_addr=b10e0090 pf_ip=132dbc from 00 <NULL>)

2b429ee84c base: Dispatch server signal in entry point
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.

2d9d55a6d3 tool: create_uboot
To make the creation of a bootstrap medium for most ARM platforms more
comfortable this tool shall bundle all the different U-Boot source
states, patches, and MMC preparation rules that we gathered over the
year for that purpose. As input, the tool merely needs the targeted
platform (analogous to the platform parameter of 'create_builddir'). By
now, 'hw_wand_quad' is the only supported platform. Further platforms
can be added successively. As output, the tool creates a head image file
of small size (8MiB) that can be copied (dd) with offset 0 to the MMC.

ce354d6fd9 linux: improve diagnosis on exception handling
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.
