fix(kernel/default_converter): broken optimization
...
we must also check the universe levels when applying the optimization for
constraints of the form:
f.{l_1 ... l_k} a_1 ... a_n =?= f.{l_1' ... l_k'} b_1 ... b_n
The optimization tries to avoid unfolding f if we can establish that
a_i is definitionally equal to b_i for each i in [1, n]

fix(library/tactic): we must unfold untrusted macros when type checking intermediate results
...
Example: before this commit, the file librata/data/list/perm.lean would
not type check if the option -t 0 (trust level zero) was provided.
Reason: the intermediate term contained a macro, and macros are not
allowed at trust level zero.

fix(bin/linja): replace windows newline '\r\n' to unix newline '\n'
...
This should be handled by Python. However, when we use mingw-python
which acts like Unix Python with Native Windows Emacs, we have a problem
because mingw-python do not handle '\r'. This patch manually replace
'\r\n' with '\n' to solve the problem.
