Increase size of buffer for signals

The chan struct used to forward signals to containers was one element only,
which caused some signals to be dropped when many were being received.
Increasing the size of the chan buffer makes this much less likely to happen.

Escape control and nonprintable characters in docker ps

The docker ps command displays the user-entered command running in a container.
If that command contained \n, \t, or other control characters, they were
interpreted literally, and newlines and tabs would be printed in the output.
Escape the command string to make things more readable.

devmapper: fix reloadPool() to also specify '1 skip_block_zeroing'

createPool() and reloadPool() should be consistent with the thin-pool
table params they use.

Since createPool() specifies '1 skip_block_zeroing' reloadPool() should
too.  Otherwise, if the pool is reloaded (as is done when resizing
loopback devices) block zeroing will be enabled after the reload
completes.

devmapper: use RAMInBytes() rather than FromHumanSize()

Device Mapper needs device sizes in binary (1024) multiples.  Otherwise
kernel checks can find that the specified thin-pool device sizes aren't
a multiple of the specified thin-pool blocksize.

The name for "RAMInBytes" is likely too narrow given the new consumers
but... Also add "tebibyte" support to RAMInBytes.

devmapper: Add option for specifying the thin pool blocksize

Add dm.blocksize option that you can use with --storage-opt to set a
specific blocksize for the thin provisioning pool.

Also change the default dm-thin-pool blocksize from 64K to 512K.  This
strikes a balance between the desire to have smaller blocksize given
docker's use of snapshots versus the desire to have more performance
that comes with using a larger blocksize.  But if very small files will
be used on average the user is encouraged to override this default.

Update documentation noting that SIGCHLD is not proxied.

Docker's --sig-proxy option sends all signals but one to a container. The
exception s SIGCHLD, which is deliberately ignored as it doesn't make sense to
send such a signal to a process in a container. Documentation updates will make
this less confusing if anyone does attempt to do this.

Document memory limit sizing in manpages

The -m flag permits the setting of a memory limit when running a Docker
container. The actual limit set must be a multiple of page size on Linux, so
whatever number the uses passes in will be rounded up if needed. Document this
behavior to prevent confusion. Also fixed several small formatting and grammar
issues in the docker run manpage.
