Christian Helmuth 6df8b44616 platform/x86: support 64-bit base address registers
The API still exports 32-bit address and size values only, which works
as the actual MMIO resources are allocated in platform_drv internally.

Christian Helmuth 11a7ac0536 acpi_drv: reduce capability quota requirements
Map ACPI tables entirely as one dataspaces (not page-by-page). Note, the
current approach does only merge overlapping but not consecutive I/O
memory regions, which would reduce the amount of capabilities required
even further.

Norman Feske eefe91ee41 depot_download_manager: no mtime update in extract
With the added modification-time support in the libc, the extract tool
requires a timer session, which is not plausible for the purpose of the
program.

This behavior stems from the fact that the libc implicitly writes the
mtime when closing a written file. For this update, it implicitly calls
'clock_gettime', which in turn initializes the timer subsystem within
the libc (creating a timer session).

For the extract tool, the implicitly updated mtime is useless because
the extract tool overwrites this modification time with the mtime stored
in the archive anyway. However, the dependency from a timer service
remains.

This patch explicitly disables the libc's implicit updating of the
file-modification when closing a written file.

Josef Söntgen 94b63924ed noux: add time modification
... and set initial time by using RTC session.

Up to now Noux used a monotic clock whose initial start value always
was '0' (which correlates to the start of the UNIX epoch) to provide
a notion of time. In addition it is now possible to use the RTC
session to set the initial value for use cases where having a proper
real-world time matters.

To use the RTC session the 'rtc' attribute of the '<config>' node
must be set to 'yes'. Thereby the session becomes a mandatory
dependency as Noux will not start without it.

Norman Feske 697d496093 ldso: don't strip leading path from ROM name
This patch removes ldso's builtin policy of removing any path elements
prepending the ROM module name. Instead, the ROM name is used as is.
This clears the way to access different ROM modules that share the same
name but are stored at different directories behind an fs_rom (e.g.,
/bin/bash vs. /usr/local/bin/bash).

Norman Feske c8b7710e5d libc: improve dup/dup2 in vfs_plugin
This patch replaces the naive dup2 implementation (that merely
duplicated the context pointer) by the replication of the original
FD state by re-opening the same file with the same flags and seek
position. This prevents a potential double release of the VFS handle
(the FD context). It also implements 'dup'.

Norman Feske 648bcd1505 libc: unify use of namespaces
This patch unifies the patterns of using the 'Genode' and 'Libc'
namespaces.

Types defined in the 'internal/' headers reside in the 'Libc'
namespace. The code in the headers does not need to use the
'Libc::' prefix.

Compilation units import the 'Libc' namespace after the definition of
local types. Local types reside in the 'Libc' namespace (and should
eventually move to an 'internal/' header).

Since the 'Libc' namespace imports the 'Genode' namespace, there is
no need to use the 'Genode::' prefix. Consequently, code in the
compilation units rarely need to qualify the 'Genode' or 'Libc'
namespaces.

There are a few cases where the 'Libc', the 'Genode', and the global
(libc) namespaces are ambigious. In these cases, an explicit
clarification is needed:

- 'Genode::Allocator' differs from 'Libc::Allocator'.
- 'Genode::Env' differs from 'Libc::Env'.
- Genode's string functions (strcmp, memcpy, strcpy) conflict
  with the names of the (global) libc functions.
- There exist both 'Genode::uint64_t' and the libc'c 'uint64_t'.

Norman Feske bf92232698 libc: split task.cc into multiple files
This patch is the first step of re-organizing the internal structure of
the libc. The original version involved many direct calls of global
functions (often with side effects) across compilation units, which
made the control flow (e.g., the initialization sequence) hard to
follow.

The new version replaces those ad-hoc interactions with dedicated
interfaces (like suspend.h, resume.h, select.h, current_time.h). The
underlying facilities are provided by the central Libc::Kernel and
selectively propagated to the various compilation units. The latter is
done by a sequence of 'init_*' calls, which eventually will be replaced
by constructor calls.

The addition of new headers increases the chance for name clashes with
existing (public) headers. To disambiguate libc-internal header files
from public headers, this patch moves the former into a new 'internal/'
subdirectory. This makes the include directives easier to follow and the
libc's source-tree structure more tidy.

There are still a few legacies left, which cannot easily be removed
right now (e.g., because noux relies on them). However, the patch moves
those bad apples to legacy.h and legacy.cc, which highlights the
deprecation of those functions.
