77c20e99ff feat(library/tactic/inversion_tactic): consistent orientation of generated equalities
Generated equalities in proof irrelevant environments were inverted
compared with the documentation and the proof relevant case, which
resulted in newly generated local vars replacing equivalent old ones
instead of the other way around.

11fbee269b fix(frontends/lean/parser): must save state of name_generator in parser snapshot
To provide typing and auto-completion information, we create a
background process by starting lean with the option --server.
In "server" mode, we create snapshots of the parser state.
The idea is to be able to quickly reprocess a file when the user makes a
modification. This commit fixes a bug in the snapshot operation.
It was not saving in the snapshots the unique name generator used by the parser.
By creating a fresh name generator, we may accidentally
assign the same internal name to two different constants.
This bug triggered the crash described in issue #593.

This commit fixes the test in the comment
https://github.com/leanprover/lean/issues/593#issuecomment-101768484

This commit also adds a smaller version of the problem to the test suite

16b7bc3922 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]

210cae7d6c 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

Reason: the intermediate term contained a macro, and macros are not
allowed at trust level zero.

7bae895c23 refactor(src/CMakeLists.txt): simplify conditions in if
There are many places where we do not need 'MATCHES "ON"' or 'MATCHES
"OFF"'. Reference: http://www.cmake.org/cmake/help/v3.0/command/if.html

~~~
if(<constant>)

True if the constant is 1, ON, YES, TRUE, Y, or a non-zero number. False
if the constant is 0, OFF, NO, FALSE, N, IGNORE, NOTFOUND, the empty
string, or ends in the suffix -NOTFOUND. Named boolean constants are
case-insensitive. If the argument is not one of these constants, it is
treated as a variable.
