Remove ^L characters hidden randomly in the code. Not those used in text files as delimiters.

While working on a tool that processes Erlang code and testing it against this repo,
I found out about those little sneaky 0xff. I thought it may be of help to other
people build such tools to remove non-conforming-to-standard characters.
inets: httpc improve pipelining
httpc: Enhanched error handling
inets: httpc make httpc_cancel_request/[1,2] asynchronous
The gen_event callback module expects terminate/2, not terminate/1
inets: httpc - Remove dead error handling code

Some error handling is only relevant for functions that
end up in gen_server:call and not in gen_server:cast.
asn1ct_value: Handle named INTEGERs with constraints

The asn1ct:value/2 function would crash for name INTEGERs with
constraints, such as INTEGER {a(2),b(3),z(17)} (2|3|17, ...).
PER/UPER: Correct encoding for single-value extensible constraints

An extensible constraint which is a union of single values, such as:

  INTEGER (1|17, ...)

would be incorrectly encoded.
Cope with .erlang files that print to stdout

Don't redirect standard output when auto-generating the asn1ct_rtt.erl
and asn1ct_eval*.erl source files, because anything printed form
.erlang will end up in them, probably causing a compilation error.

Introduce unconditional ERTS_ASSERT
and use that for both ASSERT and ASSERT_EXPR.
