Check the performance schema table structure.

The code in this file is implemented in pfs_check.cc

instead of pfs_server.cc, to separate dependencies to server
|
|
structures (THD, ...) in a dedicated file.
|
|
This code organization helps a lot maintenance of the unit tests.

Discrepancies are written in the server log,

|
|
return an error code:
|
|
- some differences are compatible, and should not cause a failure
|
|
- some differences are not compatible, but then the DBA needs an operational
|
|
server to be able to DROP+CREATE the tables with the proper structure,

|
as part of the initial server installation or during an upgrade.
|
|
In case of discrepancies, later attempt to perform DML against

the performance schema will be rejected with an error.
