Fix OPAM share directory in OCaml layer This commit uses process-lines instead of shell-command-to-string, as seen in ocaml/merlin#547. This fixes an issue on Windows where the external command fails, resulting in a broken load-path.

Ocaml layer init without opam. Currently the ocaml layer requires opam in order to work. However opam is only really required for an easy installation of the required ocaml binaries. The only place where opam is used instead is to add the merlin files of the merlin installed via opam instead of the merlin files from melp. This commit introduces a fallback if opam is not installed but ocamlmerlin is installed, since the melpa package of merlin is already installed through packages.

Refactor jump to definition This commit defines: - spacemacs-default-jump-handlers: a list of functions that can jump to definition in ALL modes. - spacemacs-jump-handlers-MODE: a list of functions that can jump to definition in MODE. - spacemacs-jump-handlers: a buffer-local list of functions that can jump to definition. This is made up of the values of the two previous variables whenever a given major mode is activated. - spacemacs/jump-to-definition: a function that tries each function in spacemacs-jump-handlers in order, and stops when one of them takes us somewhere new. - spacemacs|define-jump-handlers: a macro that * defines spacemacs-jump-handlers-MODE, possibly filled with initial functions * defines a function that is added to the hook of the given MODE * binds “SPC m g g” of that MODE to spacemacs/jump-to-definition This is an attempt to harmonize all the different approaches to jumping. Specifically, - Existing intelligent jump packages that work for only a single mode should go to the beginning of spacemacs-jump-handlers-MODE. E.g. anaconda for python, ensime for scala, etc. - Packages like gtags that work for several modes (but potentially not all) and which is dumber than the intelligent jumpers should go the the END of spacemacs-jump-handlers-MODE. - Packages like dumb-jump that work for all modes should go to spacemacs-default-jump-handlers. In all cases the order of the jump handlers in each list should be from most to least intelligent. Fixes #6619
