In both bytecmp and c compiler we use si:function-boundary and
si:unwind-protect-boundary where appropriate. Previously bytecmp used an ad-hoc
special variable for function-boundary and didn't mark unwind-protect at all.
Remove recently-introduced ECI package (maybe we will reintroduce it later when
we'll have a common frontend for compilers).
bc-compile is more conforming now (we validate definition and name, also our
closure compilation is a bit better, still broken though).
Also improve some error messages and add periods at the end.
We have created empty closure for instance when flet was in null lexenv. Check
for Null in close_over and create t_bclosure only for non-null lexical
environments.
Code was previously written with an assumption, that we know whenever function
crosses lexical for closure boundaries before it is compiled (and env-mark for
such boundries was LB and CB appropriately). Later it has changed, but code was
ready to work with LB and CB marks.
Fix these parts of code and replace it with a single mark ECI:FUNCTION. Also
replace CL:UNWIND-PROTECT boundry mark with ECI:UNWIND-PROTECT so we are less
dependent on use-ing CL package. Adjust comments to have this change.
We have dummy variable for that, so we refere to
(var-ref-ccb (tag-var blk))
(var-ref-clb (tag-var blk))
Brokeness comes from the fact that closures are computed after function
compilation pass-1 (and tagbody is inside). Analogous change to the previous
commit in cmpblock.
Also improve comments in cmptypes to make it clear that these parts are not
used. Further refactor could make tag inherit from variable - then we wouldn't
have a dummy variable and unnecessary fields whatsoever.

This optimization doesn't buy us much but it doesn't cost us anything
either. Note that it emits c1form in case of expression what means that
expression won't be promoted to top-level form after the reduction.
It didn't wake up all processes to check the condition what caused n+1 lag in
condition check for signal-process (when called with n>1). Fixes#421. No
regression test, because this is already tested in sem-signal-* tests (they were
failing).
bytecompiled functions may not have a name (i.e lambda assigned to
smothing). Recognize that fact, so when we read back such functions
from file we can call bc-compile on them. Fixes#313.
