This patch makes MAKEDEV.sh use the /bin/nullpriv wrapper so that the
storeio translator serving /dev/zero is started without any unix
privileges.
* sutils/MAKEDEV.sh (mkdev): Use /bin/nullpriv for /dev/zero.

runsystem.sh checks whether /servers/socket/1 exists and creates it
using settrans -c if it does not. But at this point in the boot the
root filesystem is normally not writable. This patch fixes this.
* daemons/runsystem.sh: Make sure / is writable before attempting to
set up pflocal.

Remove support for transparently ungziping executables from the exec
server. The code in question makes the exec server unnecessarily
complex and since the exec server is an essential process, crashing it
makes /hurd/init crash the whole system.
Since the gzip code is not thread-safe, all access to it is
serialized, so there is a trivial way for one user to delay another
users gzipped executables for some unspecified time.
This can be accomplished by padding any program with easily compressed
data, zipping it and executing it. Using such a program as an passive
translator and then triggering its execution by the filesystem
translator also stalls any requests to that filesystem (observed using
the libdiskfs-based ext2fs).
Since compressed executables cannot be mapped into the memory, they
have to be uncompressed into allocated memory first. This is slower
and any user with access to the exec server can make it allocate
arbitrary amounts of memory. If the Hurd had proper memory accounting,
this would probably be a way around it.
So the compression support in exec seemingly creates various issues
for little value, at least with the abundance of nonvolatile memory
available today.
* exec/Makefile: Remove gzip related files.
* exec/exec.c: Remove anything #ifdef GZIPped.

The mtab translator provides an mtab file that is dynamically created
on demand. It is populated with information about active translators

translator tree. It can also be invoked as normal program that prints
the requested information to stdout.

* trans/Makefile: Build mtab.

Return information about the source of the receiving filesystem.
If the concept of a source is applicable, SOURCE should refer to
the source of the receiving translator and should be a description
considered appropriate in the context of the translator. For
example for the case of block device based filesystems, SOURCE
should be the file name of the underlying block device.
