Geoffroy Van Cutsem 8b16be9185 Remove "All rights reserved" string headers
Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

Junjie Mao 9781873e77 HV: treewide: fix violations of coding guideline C-TY-12
The coding guideline rule C-TY-12 requires that 'all type conversions shall
be explicit'. Especially implicit cases on the signedness of variables
shall be avoided.

This patch either adds explicit type casts or adjust local variable types
to make sure that Booleans, signed and unsigned integers are not used
mixedly.

This patch has no semantic changes.

Li, Fei1 a1ac585b85 hv: add brackets to make operator expression more readable
v1-v2:
Bypass this case:
When binary arithmetic operators of different precedence (e.g. '+'
and '*') are mixed in an expression, parentheses are added to the
sub-expressions using the operator with a higher precedence.

v1:
The operator precedence rules are complicated and it is easy to make a mistake.
So add brackets to make operator expression more readable.

Junjie Mao f691cab994 HV: treewide: terminate 'if .. else if' constructs with 'else'
MISRA C requires that a 'if' statement followed by one or more 'else if'
statement shall be terminated by an 'else' statement which contains either
side-effect or a comment, to ensure that conditions are considered
exhaustively.

Note that a simple 'if' statement is not required to be terminated by 'else'.

This patch fixes such violations by either refactoring the code or add the
'else' statement with either a comment (describing why this case can be skipped)
or logging the event. It may not be satisfactory for the release version where
logging is no-op, but properly handling these non-trivial cases is out of the
scope of this patch.

v1 -> v2:

    * Fix unintended semantic changes in add_(msix|intx)_remapping and
      io_instr_vmexit_handler.
    * Simplify boolean checks in vpic_ocw2.
