v1.5 - BACKWARD_CXX_SOURCE_PREFIXES and many bug fixes

Summary of changes in no particular order.

Arnaud Botella (1):

  Update BackwardConfig.cmake

David P. Sicilia (5):

  Allow specifying list of source file search paths in environment variable.
  
  This is useful for binaries (using backward-cpp) that are built with
  relative source file paths.  In such a situation, backward-cpp will
  generally not be able to locate the source files.  This change allows
  the user to specify a delimited list of search paths in the following
  environment variable: BACKWARD_CXX_SOURCE_PREFIXES

  The paths are separated by semicolons on Windows and colons otherwise.
  When the environment variable is set, those search paths will be tried
  first.  If they do not yield any valid files then backward-cpp will
  fall back to current behavior.

  Address some reviewer comments:
  Use const char[] for delimiter string instead of macro.
  Put delimiter string into `backward::details` namespace.

Evan Klitzke (2):

  fix a memory leak when __cxa_demangle reallocs
  fix bad pointer comparison in libdwarf backend

Forrest Voight (3):

  Extracted duplicated code for `get_argv0` and `read_symlink`
  Handle executable being deleted or replaced by directly opening `/proc/self/exe` rather than file it links to. Fixes issue #146.
  Call std::getline with an lvalue std::ifstream rather than an rvalue. Older libstdc++ versions (e.g. 4.8.2) don't have the rvalue overload of std::getline. This fixes this error when compiled with libstdc++ 4.8.2:

Jiaxun Yang (1):

  Add mips support

John Salmon (2):

  Improve portability to non-glibc Linux systems
  StackTraceImpl::operator[] is const

Marco Magdy (2):

  Add missing ref qualifier
  squash! Add missing ref qualifier to the other overload

Michael Truog (2):

  Fix compilation for GCC (tested with 5.4.0)
  Fix for binutils 2.34

Michal Rostecki (1):

  cmake: Use GNUInstallDirs for libdir and includedir

Nikos Skalkotos (1):

  Fix unknown pragma warning in gcc

Pierre Kestener (3):

  check if compiler is nvcc/nvcc_wrapper to trigger off cxx gnu extensions and pedantic error flags
  Merge branch 'master' of https://github.com/bombela/backward-cpp into nvcc_wrapper
  make sure to detect nvcc compiler even if used embedded in mpi compiler wrapper

Zsolt Parragi (4):

  Build tests by default when backward is a top level project
  Use a macro instead of direct noinline attributes.
  Making tests less platform dependent.
  Windows (Clang9, MSVC2017) implementation
