0511091e8a Streamline copyright notices across the codebase. (#1473)
Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.

Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):

"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)

This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.

Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.

8edab96162 Fix JMEM_HEAP_END_OF_LIST for pointers larger than 32 bits
For 64 bit pointers, 0xffffffff as end-of-list marker pointer does
not work, as the marker is expected to be greater than the start
address of the heap area (and also max 0xffffffff away), but on 64
bit systems, the heap can start on higher addresses, i.e., above
0x100000000.

This patch changes JMEM_HEAP_END_OF_LIST from pointer to offset.

a2d5acb43c Follow-up refactoring of logging-related parts
This patch:
* Ensures that all calls to `jerry_port_log` in jerry-core happen
  via macros defined in jrt.h. Also, it unifies the names of those
  macros: as `JERRY_ERROR_MSG` and `JERRY_WARNING_MSG` gave a good
  pattern that was well aligned with the naming scheme of the log
  level enum, `JERRY_DLOG` and `JERRY_DDLOG` were rewritten to
  `JERRY_DEBUG_MSG` and `JERRY_TRACE_MSG`.
* Ensures that all debug logging code parts of jerry-core (i.e.,
  memory statistics, JS byte-code dumps, and RegExp byte-code
  dumps) are guarded by macros: `JMEM_STATS`,
  `PARSER_DUMP_BYTE_CODE`, and `REGEXP_DUMP_BYTE_CODE`, which in
  turn are controled by cmake build system feature flags
  `FEATURE_MEM_STATS`, `FEATURE_PARSER_DUMP`, and
  `FEATURE_REGEXP_DUMP`.
* Ensures that all debug logging functionalities can be controled
  during run time (provided that they were enabled during build
  time): the engine has `JERRY_INIT_MEM_STATS[_SEPARATE]`,
  `JERRY_INIT_SHOW_OPCODES`, `JERRY_INIT_SHOW_REGEXP_OPCODES` init
  flags, and the default unix/linux command line app has
  corresponding command line switches.`
* Drops `FEATURE_LOG`, `JERRY_ENABLE_LOG`, and
  `JERRY_INIT_ENABLE_LOG`, as their name was misleadingly general,
  even though they mostly controled the regexp engine only. The
  above-mentioned `*REGEXP*` things mostly act as their
  replacements.
* Updates build, test, and measurement tool scripts, and
  documentation.

e7ec053362 More gc-friendly property hashmap allocation.
- New allocator is added that returns null on out of memory, property hasmap create uses this allocator for now.
- Property hashmaps of objects are removed durring a high severity gc.

Follow up patch is in progress.

3a78d30897 Introducing global context.
Currently the static variables of the allocator are moved into a
global structure.

The future plan is supporting multiple context models with different
advantages and disadvantages. Users can select the most appropriate
context model for their own use case. This context model must be
selected at compile time using compiler defines.

Currently only one model is implemented, which will be the default
context model: the context is stored in global variables, so only
a single context is available which always exists.

92bb551d45 Change 'mem' namspace to 'jmem'
The 'mem_' prefix is too general, so it might clash with
symbols in other libraries. Renamed the directory, file,
funtion and type names.
