When metaversion of libvintf updates, --init-vintf option
always uses the highest metaversion, breaking tests. These
tests should work with any metaversion of libvintf. The HAL
sections should be focused on.

If any error comes up when invoking debug, write fqname and the error
message to the error output stream.
Test: manual. Add addPostCommandTask to a HAL that keeps writing to the
fd after debug() finishes. lshal debug terminates with fqname and
the error message `timeout reading from pipe, output may be truncated.`

A HAL can't be retrieved unless it is in the VINTF manifest. This
design decision was made so that people add HALs to the manifest as
early as possible (this makes sure that the manifest is accurate on
a change by change basis).
A common problem people face is seeing a HAL in lshal, but because
of the above, it can't be retreived. Currently, in order to see
manifest information, you either have to dig into the lshal settings
or dig into the filesystem. Since one of the most common debugging
steps for a HAL is to check lshal for the HAL, having the information
right here will help. Even though it doesn't explicitly say what the
implications of 'FM' or 'DM' are, reading the lshal help gives a
reasonable idea of this, and when a snippet of lshal is shown (either
in a bugreport/email etc), it will contain the information required
to diagnose the issue.
This CL also fixes a couple bits of documentation in lshal and adjusts
the formatting of the output slightly to break up table descriptions
from the output.

In ~PipeRelay, since the data is no longer needed,
just close the fd before joining the thread.
In previous code, 'lshal debug' can hang:
- lshal read() waiting for data in RelayThread
- lshal send fd to service in main thread
- service close the fd
- service returns in debug() call
- lshal calls ~PipeRelay
- lshal read() is still blocking because it does not
receive the signal
But, since the service has already end the debug()
call, the fds can be closed to bail out from blocking read().
Test: 'while true; do lshal debug ...; done' does not hang
