Brad King 86578eccf2 Simplify CMake per-source license notices
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool.  Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience.  Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.

Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices.  It also references version control
history for more precise information.  Therefore we no longer need to spell
out the list of Contributors in each source file notice.

Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing".  The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.

Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically.  Manually fix up shebang lines and trailing
newlines in a few files.  Manually update the notices in a few files that the
script does not handle.

Brad King 0cbaaf2dc3 GenerateExportHeader: Fix add_compiler_export_flags regression
The mechanical conversion in commit 5d0d980d (Use string(APPEND) in
Modules, 2016-07-28) accidentally introduced use of

  string(APPEND ... PARENT_SCOPE)

Split that into the string(APPEND) and set(PARENT_SCOPE) pieces.

Andreas Schuh be5a8973c3 GenerateExportHeader: Do not define DEFINE_NO_DEPRECATED (#16022)
Previously we allowed this definition to persist outside our header.
This would cause conflicts across multiple such headers because the name
was always the same.  Fix this by avoiding the definition altogether.

James Johnston 060442c2e8 Embarcadero: Check code using CMAKE_CXX_COMPILER_ID and CMAKE_C_COMPILER_ID.
The CMAKE_CXX_COMPILER_ID and CMAKE_C_COMPILER_ID variables are set to
"Borland" for older versions of the compiler.  Newer CodeGear/Embarcadero
compilers will have those variables set to "Embarcadero".  Search for lines of
code referencing both the variable name and Borland to be sure that they also
refer to Embarcadero.

Brad King 69fe5920b3 GenerateExportHeader: Avoid if() quoted auto-dereference
When testing CMAKE_CXX_COMPILER_ID values with if(MATCHES),
do not explicitly dereference or quote CMAKE_CXX_COMPILER_ID.
We want if() to auto-dereference the variable and not its value.

Stephen Kelly 7e24997fed GenerateExportHeader: Generate only C identifiers as defines
The variables in this module are used to configure a header file
with defines whose name depends on the name of the target.

As valid names of targets may be invalid for use as defines, convert
the names of the defines used to C identifiers first. This is already
done in C++ code for the DEFINE_SYMBOL property.

This is not as simple as ensuring that the BASE_NAME is a C identifier,
because most of the define names are configurable, and because use of
a BASE_NAME which is not a C identifier, such as 4square can become a
C identifier by specifying a prefix in the generate_export_header
macro.

Stephen Kelly 7ffef5024a GenerateExportHeader: Allow use of of this macro with MODULEs.
The significant issue with MODULEs is that on Windows, the exported
symbols must be dllexported and they are not imported.

In other export macro implementations this is done by defining an
export macro outside of any ifdef which depends on definitions set
on the command line. However, with cmake we already expect the
DEFINE_SYMBOL to be defined, so the regular EXPORT macro can be
used by such plugins.

Rolf Eike Beer c28e276948 GenerateExportHeader: improve compiler identification
Use CMAKE_<LANG>_COMPILER_VERSION instead of calling the compiler. This macro
predates those useful variables. This also fixes the issue that g++ version
detection was not working if C language was not enabled.

Alex Neundorf 54e1f6f5a5 GenerateExportHeader: use double quotes around _gcc_version
The GenerateExportHeaders test was failing on one machine, the version
could not be determined there, so the _gcc_version was empty,
so the first argument to if() was empty, so it complained:
http://open.cdash.org/testDetails.php?test=135623436&build=2016288
Use double quotes to turn the non-existant first argument into an empty
string.

Marcus D. Hanwell 41e2b1d824 Make add_compiler_export_flags a function again.
Making this a macro had unintended issues on (among others) Windows
compilers. Moving it back to being a function using PARENT_SCOPE still
satisfies the use case where we simply want to obtain the extra flags.

Marcus D. Hanwell 6a10deb670 Made ADD_COMPILER_EXPORT_FLAGS into a macro.
It adds to the CMAKE_CXX_FLAGS (as before), or populates the supplied
