Properly clear the last entered character

When enter is pressed, passwd[len] will be set to '\0'. Pressing
backspace is supposed to remove the last entered character.

But currently, the clearing has an off-by-one, as in setting
passwd[len] to '\0' just like enter would do.

You can also verify it by imagining len=1 and that it's impossible to
clear passwd[0] by pressing backspace with the current code.

syntax fix

there can only be one window in the event

Fix resize with multiple monitors and portrait mode

When connecting/disconnecting a portrait monitor, the
XRRScreenChangeNotifyEvent height & width are reversed due to the XRandR
rotation; detect this and DTRT.

move config.h inclusion after type declarations

Unboolify slock.c

Use explicit strcmp() instead of inlining it

Makes it a tad more readable; the previous "optimization" will be done
by the compiler anyway.

No need for oldc to be static

Use NUL character constant explicitly

Keep the line-lengths at bay

This makes the code more readable and prevents wraparounds in the
editor.
