zcash-cli: arguments privacy
----------------------------
The RPC command line client gained a new argument, `-stdin`
to read extra arguments from standard input, one per line until EOF/Ctrl-D.
For example:
$ src/zcash-cli -stdin walletpassphrase
mysecretcode
120
^D (Ctrl-D)
It is recommended to use this for sensitive information such as private keys, as
command-line arguments can usually be read from the process table by any user on
the system.
