7e11c5cf6e fix(src/util/file_lock): ignore failure to create locks on read-only file systems 
EACCES is already ignored when creating lock files.  In this case we
assume that the file to be locked is part of the system-wide
installation.  On NixOS however, the file system containing system
packages is mounted read-only, and open(2) returns EROFS.

Leonardo de Moura
54f2c0f254 feat(library/blast/forward): inst_simp should use the left-hand-side as a pattern (if none is provided by the user) 
The motivation is to reduce the number of instances generated by ematching.

For example, given

   inv_inv:  forall a, (a⁻¹)⁻¹ = a

the new heuristic uses ((a⁻¹)⁻¹) as the pattern.
This matches the intuition that inv_inv should be used a simplification
rule.

The default pattern inference procedure would use (a⁻¹). This is bad
because it generates an infinite chain of instances whenever there is a
term (a⁻¹) in the proof state.
By using (a⁻¹), we get
   (a⁻¹)⁻¹ = a
Now that we have (a⁻¹)⁻¹, we can match again and generate
   ((a⁻¹)⁻¹)⁻¹ = a⁻¹
and so on

f177082c3b refactor(*): normalize metaclass names 
@avigad and @fpvandoorn, I changed the metaclasses names. They
were not uniform:
- The plural was used in some cases (e.g., [coercions]).
- In other cases a cryptic name was used (e.g., [brs]).

Now, I tried to use the attribute name as the metaclass name whenever
possible. For example, we write

   definition foo [coercion] ...
   definition bla [forward] ...

and

  open [coercion] nat
  open [forward] nat

It is easier to remember and is uniform.

Remark: the lock are not being erased on Windows.
I tried different solutions based on MoveFileEx and DeleteFile.
None of them worked. The one based on MoveFileEx

        MoveFileEx(m_fname.c_str(), NULL, MOVEFILE_DELAY_UNTIL_REBOOT);

seems to delete the file after REBOOT.
But, this is not very useful.

193a9d8cde refactor(library/norm_num): avoid manual constant name initialization 
@rlewis1988 We group all Lean constants used in the C++ code at
src/library/constants.txt

Jeremy and Floris check this file before renaming constants in the
library. So, they can quickly decide whether C++ code will be affected
or not.

We also have a python script for initializing the C++ name objects.
To use the script:
   - go to src/library
   - execute
       python ../../script/gen_constants_cpp.py constants.txt

It will create the boring initialization and finalization code, and
declare a procedure get_<id>_name() for each constant in the file constants.txt.

I also move the norm_num1.lean to the set of unit tests that are
executed whenever we push a commit to the main branch.

I found an assertion violation at line 606. Could you take a look?

Best,
Leo
