Also add tests for not, true and false

This takes into account that "introduce" actually split negative
conjunctions.

This is implemented using an attribute that is detected when a
transformation introduces the hypothesis.
Added for assertion_kind and requires.

This shows where the colors/cursor are located on the source code when
selecting a goal.
This also contains an experimental oracle based bench for keeping track of
this information.

This allows a strategy to call provers with the default timelimit/memlimit
parameter.
Example: "c CVC4,1.5 %t %m"

Remove set_session_timelimit/memlimit from server_utils: put them in
controller_itp so that they directly edit the configuration of the
controller.
Edit parser of strategies to allow %t and %m.

This command is added only in the Tools menu. It is not in the context
menu and it cannot be called from the command line. Calling this will
trigger a popup to prevent users mistake.

Replace split_all_full by split_vc as first transformation used by Auto

This adapts the ConnectionError exception to output a nice message in Why3

* src/driver/prove_client.ml
Register the new exception so that it is nicely printed.

When the socket file cannot be created, raise an exception instead of
exiting.  This allows a nice error message to be printed.

* prove_client.ml
(client_connect): in case of error, do not exit, but raise exception

(cherry picked from commit b18ffc3f742cf8738533994119857328e7dc8633)

Add an option in the preferences to disallow the automatic jump after a
goal is completed. Jump can still be performed by calling next in command
line.

Also fix induction_pr_arg so that it adds the right attribute inside the
goal.

This helps *only* to provide clearer error messages.

This fixes a bug that printed an empty string for 0 if the number of digits was unspecified.

This was triggering a popup when too many arguments are given to a
transformation (because the exception was considered fatal by default).
