core: add generic struct ts_session

As a step in making room for Secure Partitions (SPs) running at S-EL0
add a Trusted Service (TS) abstraction. Both TAs and SPs is a TS.

Adds the generic struct ts_session. All future sessions structs
(currently only struct tee_ta_session exists) should add this struct to
allow generic session operations.

With this struct comes new functions replacing previous struct
tee_ta_session oriented functions. The following functions are replaced
as:
tee_ta_get_current_session() -> ts_get_current_session()
tee_ta_push_current_session() -> ts_push_current_session()
tee_ta_pop_current_session() -> ts_pop_current_session()
tee_ta_get_calling_session() -> ts_get_calling_session()

ts_get_current_session() is changed compared to its predecessor to
panic() in case of failure to return a valid pointer.

A new function ts_get_current_session_may_fail() is added to handle an
eventual case where a return NULL session may be handled.

Remove 'All rights reserved' from Linaro files

The text 'All rights reserved' is useless [1]. The Free Software
Foundation's REUSE Initiative best practices document [2] does not
contain these words. Therefore, we can safely remove the text from the
files that are owned by Linaro.

The scancode tool [3] was used to double check the license matching
code in the Python script. All the licenses detected by scancode are
either detected by spdxify.py, or have no SPDX identifier, or are false
