sysctl: restore old -p handling
The previous version of sysctl had the form:
sysctl -p [file]
In other words, it required a space between the -p and the [file].
Omitting the space would lead to an error.
The new version though is the opposite:
sysctl -p[file]
In other words, it requires there to not be a space.
Considering the old behavior has been around for a decade, and runtime
checking for this mismatch in behavior is silly, and supporting the old
syntax is trivial, add support for it.
When '-p regexp' is glob is used to make reqular expression to be
expanded to argument list, which also means that -p option will
allow multiple files being specified as input.

top: address a defect with the library PROC_PID flag
The library does not weed out potential duplicate PID
values when sampling with the PROC_PID flag. This was
treated as merely an inefficiency by top and safely
ignored prior to the advent of forest view mode.
Now, however, if the -p switch duplicates certain PIDs,
*and* those processes have no PPID, *and* top's forest
view mode is active or activated, then a SEGV will be
generated (and caught).
This rather obscure buglet is thus limited to pid #1
(/sbin/init) and pid #2 (kthreadd). With any other
duplicate PIDs the worse case scenario was a '?' in
place of the usual forest view artwork.
This commit silently ignores any duplicate process ids

top: correct loss of keystrokes paste capability
When top introduced true line input editing, the
ability to paste keystrokes was lost. This remains
a necessary evil so that top has an opportunity to
translate cursor motion keystrokes into terminfo
escapes during line input. Motion keys themselves,
of course, can never be pasted.
If pasting ever became more important than input
editing, then native termios support should have been
available via a define called TERMIOS_ONLY. But a
recent commit, eliminating what was thought to be
obsolete logic, rendered the alternate linein()
function virtually useless.
Similar to top-3.2.8, when native termios input is
functional, these abberations can be experienced:
. cursor motion keys will appear as escapes
. excessive input can cause line wraps
. ^Z during i/p is not be honored until <Enter>
. SIGWINCH during i/p corrupts screen temporarily
In hindsight, it now seems that the ability to paste
keystrokes may indeed outweigh any shortcomings of
native termios support. This is especially true if
one is preparing to search ('L') for some lengthy
process command line contined in the clipboard.
Thus, this patch fixes the alternate linein() function
and changes TERMIOS_ONLY to TERMIO_PROXY so that top
now defaults to using native termios input. In turn,
that will restore the paste keystrokes capability.
