top: fix "top </dev/null" case (by Cristian Ionescu-Idbohrn)

now will try reading for 1-2 seconds before declaring that there is no match.
This fixes a very common annoyance with long manpages.

screen update. Makes "man bash", [enter], [/],
<enter search pattern>, [enter] more usable - manpage
draws as you enter the pattern! Yay!!
less: fix bug where backspace wasn't actually deleting chars
less: "examine file with empty name" doesn't abort anymore.
libbb: add "all fatal signals" mask.

which sets same handler for many signals. sig_catch is nuked
(bb_signals_recursive is more descriptive name).

trylink: explain how to modify link and drastically decrease amount
of padding (unfortunately, needs hand editing ATM).
*: add ALIGN1 / ALIGN2 to global strings and arrays of bytes and shorts

fill whole 1st screen (was "screen sans one line");
fall back to cat if redirected or no ctty
less: fall back to cat if no ctty (was exiting)

in input taken so far.

no preceding prototype

|

less is officially declared PAGER-capable! ;)
(this includes viewing of manpages)

these are resulting fixes
|
|
|
|
|
|
But we do not read entire input anymore up-front.

small fixes. [prev commit also added control char filtering
on input (e.g. regexp input, filename input for 'E' etc)]
|
|
user interaction if stdout is not a tty.
size optimizations
|
|
Doesn't die horribly on binary files anymore.
In fact, they _100%_ work now. Control chars
are in reverse video, including DEL and that idiocy of VT-10x,
Meta-ESC [inventor of which should be prohibited from reproducing].
Regex search is fixed also. When you specify search ('/' key),
control chars turn into dots (unhighlighted),
and found occurrences highlighted instead. This is reversible.
Memory management fixed (was leaky as hell) and optimized.
Linewrapping fixed and thoroughly tested.
Max buffer size made configurable.
~ 600 bytes saved.
