Solution: Make calling a lambda faster. (Ken Takata, closesvim/vim#5727)

Port "uf_flags" constants from patch 8.2.1054 to sync with Vim.
Port user_func_error() from patch 8.2.0149.
Port Test_lambda_scope() changes from patch 8.1.0736 so that it passes.
Problem: Error when defining a Lambda with index of a function result.
Solution: When not evaluating an expression and skipping a function call,
set the return value to VAR_UNKNOWN.

- Call test_garbagecollect_now(), as Vim does.
- window_split_tab_spec.lua: Put cursor at bottom of :terminal buffer so
that it follows output.
- inccommand_spec.lua: Increase timeout to allow 2nd retry.

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: 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.
