Subject: [PATCH 2/2] maint: Remove uses of the 'register' keyword.

* libicmp/*.c: Don't use the 'register' keyword when declaring
variables or arguments.
* libinetutils/*.c: Likewise.
* libtelnet/*.h: Likewise.
* libtelnet/*.c: Likewise.
* src/*.c: Likewise.
* talk/*.c: Likewise.
* telnet/*.c: Likewise.
* telnetd/*.c: Likewise.
