Problem: A funccal is garbage collected while it can still be used.
Solution: Set copyID in all referenced functions. Do not list lambda
functions with ":function".

Problem: Leaking memory when redefining a function.
Solution: Don't increment the function reference count when it's found by
name. Don't remove the wrong function from the hashtab. More
reference counting fixes.

Problem: Using function() with a name will find another function when it is
redefined.
Solution: Add funcref(). Refer to lambda using a partial. Fix several
reference counting issues.

Problem: User defined functions can't be a closure.
Solution: Add the "closure" argument. Allow using :unlet on a bound
variable. (Yasuhiro Matsumoto, Ken Takata)

Problem: Using submatch() in a lambda passed to substitute() is verbose.
Solution: Use a static list and pass it as an optional argument to the
function. Fix memory leak.

Problem: filter() and map() either require a string or defining a function.
Solution: Support lambda, a short way to define a function that evaluates an
expression. (Yasuhiro Matsumoto, Ken Takata)

Problem: Cannot detect a crash in tests when caused by garbagecollect().
Solution: Add garbagecollect_for_testing(). Do not free a job if is still
useful.

Note: This does not remove some intentional legacy usages of strncpy.
- memcpy isn't equivalent because it doesn't check the string
length of `src`, and doesn't zero-out the remainder of `dst`.
- xstrlcpy isn't equivalent because it doesn't zero-out the
remainder of `dst`. Some Vim logic depends on that (e.g.
ex_append which calls vim_strnsave).

While a job callback is active, it may be invoked again. Since the
data handled by the first invocation of the callback hasn't been marked
as consumed, the subsequent invocation will see the same data.

This fixes a use-after-free noticed by ASAN which would occur when a
dictwatcher was still active on a dictionary when the dictionary was
freed.
fun! MakeWatch()
let d = {'foo': 'bar'}
call dictwatcheradd(d, 'foo', function('...'))

Do _not_ set v:shell_error on parameter validation error.
system([...]) does not invoke a shell, so this change is somewhat
questionable. But `:help v:shell_error` is sufficiently vague to allow
-1 in this case.
