BUG#28915716 MEMSET IS NOT A PROPER FUNCTION TO ERASE SENSITIVE DATA

The buffers used to temporarily store the passwords obtained from the
user were not being properly cleaned, in some cases memset was being
used to "cleanup" the buffers and in other cases not even that.

memset may be optimized away (under the as-if rules) if the object
modified by this function is not accessed again for the rest of its
lifetime, letting the password data available in the memory buffer.

This patch replaces memset with functions that are excluded by this
optimization, explicit_bzero in linux and SecureZeroMemory in windows
eliminating the potential risk.

BUG#27677227 SILENT ASSUMPTION WHEN CONFIGURING CLUSTER WITH X PROTOC…

…OL DISABLED

When a cluster is created on a server that doesn't have the X Plugin
enabled, a silent assumption is made about the X Protocol port value.

The port value is calculated based on a default assumption that the X
Protocol port is equal to value of the classic protocol * 10. Such value
in stored in the metadata schema under the addresses column of the
instances table, having the value of 'mysqlX'.

Such assumption cannot be done and the address information related to
the X Protocol should only be stored under 'mysqlX' if the protocol is
enabled.

This patch fixes the issue by making sure that the value of 'mysqlX' is
only stored for instances on which the X Protocol is enabled. Otherwise
no value is stored.

Added unit-tests for regression.

Bug #28242573 MYSQLSH NOT DISPLAYING THE BUILD TYPE (COMMERCIAL) AS P…

…ART OF THE VERSION INFO

The version info has been updated to properly display the build type
as part of the version info on the missed use cases:

- The banner printed when the shell is started
- The banner printed when the --help argument is used

BUG#27809310: SHELL.GETSESSION() CAUSES CRASH IF NO SESSION IS ESTABL…

…ISHED

A crash was generated when the function was called and no session
was established. The problem is that when a null object is assigned
to a Value, it still indicates it is an object and when attempting
to translate the value to JS/PY it crashes.

The fix consist on adding validation to the Value constructor to
make it set the type to NULL if the assigned object is Null.

(cherry picked from commit 8e1858b65f71e42ee8f4fe342a6240fbcb69d159)

Fix to add updated contents of License book

Fixed Windows test failures:

Command_line_test.bug24905066 is failing on windows because the Shell is
not recognizing the named-pipe identifier (.) as equivalent to
'localhost'. A possible solution would be to use 'localhost' but this
actually needs to be fixed in the shell.

Shell_js_dba_tests.configure_local_instance is failing on windows
because of a wrong log validation which is expecting the string
"mysqlprovisioning" instead of "mysqlprovisioning.zip"

Shell_js_dba_tests.dba_cluster_add_instance is failing on windows
because of a wrong path splitting logic.

- Added "/usr/share/mysqlsh/prompt/" to the Deb packages

- Exclude the "include" directory from Deb packages
- Made the Deb build fail if not all installed files are packaged
- Minor changes to the RPM and Deb specification to remove the "include"
  and "lib" directory, if exists, before starting packaging
