24b1f269be Remove Packet_ref from File_system::Packet_descriptor
The intention of Packet_ref was to allow clients to place opaque
references into the packet descriptor itself, which could be observed on
packet completion. Currently no component in our sources uses this
feature and beyond that it is questionable if it should be used at all:
If the server tampers with the ref the client may easily be confused
into observing an incorrect or invalid context. It seems better to
remove the opaque context from the descriptor and leave the actual
implementation to the client and its needs.

e3be65833f vfs: decouple file-system factory from libc
This patch moves the VFS file-system factory to a separate vfs library
that is independent from libc. This enables libc-less Genode programs to
easily use the VFS infrastructure.

When returning early on directory operations, file systems that might
be able to handle the request but come after the current one are not
tried.

Instead of returning an uint64_t value, return a structured time stamp.
This change is only visible to components using Rtc_session directly.

bf158017da vfs: really write _count_ bytes in log file system
Genode::strncpy() enures the destination string is null terminated by
writing a null-byte. In this case, the null-bytes always overwrote the
last character of the output byte stream.
