Our ffi isn't uffi 2.0 compatible and most systems wants this, when
they say (require 'uffi). Also if system has asdf dependency on
quicklisp) we have package name error.
We'll depend with UFFI 2.0 compability on cffi-uffi-compat, what is
the saniest approach. Some ECL specific patches will land there soon
to improve performance - no internal FFI api will change. It's just
nick removal.

Some compilers doesn't allow putting function pointers when parameter
type is declared (void *), but it's necessary if we want to use
callbacks. Fixes#99.

This is necessary if we want to retrieve function name from compiled
binary, what is necessary if we want to use unique names for this
function. This is necessary for fix of issue #41.

Both byte and C compilers didn't bind lexically *readtable*, what lead

Reader had problems with converting case. Firstfully, it did convert
case for character literals. Second, it didn't convert characters for
some specific symbol cases (especially when some were escaped). Fixes

Altough short-float is now implemented as single-float, there are
clear signs that there were attempts / was separate implementation of
that type with partly-abandoned efforts. This patch shapes a bit code
in predlib.lsp and adds comments in appropriate places, that this
files needs to be modified, if such separate implementation occurs.

When function is a closure, all lexical environment were reinitialized
on each function call, because it was expanded multiple times. Do it

Previous commit overgeneralized. Handle just one particular corner
situation, when print-object leaks from standard-object to builtin
class T.
Signed-off-by: Daniel Kochmański <dkochmanski@turtle-solutions.eu>
Corner case. When user despite spec defines method `print-object'
specialized on standard-object and calls call-next-method,
`print-object' specialized on T called `write', which triggers
original `print-object' specialized on `standard-object'.

Remove `ifdef' against GC version with hack - if GC too old use

A lot of code was duplicated due to creating descriptors for output,

This makes `stderr` same class citizen as `stdout` and `stdin`. In
order to make it work structure process has been changed to be able to
handle stream_error and index of `exit-code` and `status` are
1+. Access to stream is possible via last value of run-program, which
returns process itself.

When stack overflow condition is risen, to throw cerror stack limit
has to be raised by pre-allocated margin. This function resets stack
limit to original value. The only argument is stack designator.

It is different from stack size, because limit is space available to
user, while stack size is larger by safe_area necessary to act on
stack overflow conditions.

Some functions were setting size of stack to provided value, while
other added (* 2 margin) to it, what wasn't consistant. Now each
function treats provided size as a limit and adds margin to it.
