Major code cleanup. Split tramp.el into tramp.el and tramp-sh.el.
* Makefile.in (TRAMP_SRC): Remove tramp-fish.el. Add tramp-sh.el.
* net/tramp.el (top): Don't show loading message. Require just
'tramp-compat, everything else is required there. Use
`ignore-errors' where appropriate.

| 25 | |||
| 26 | ;; Access functions for FIles transferred over SHell protocol from Tramp. | ||
| 27 | |||
| 28 | ;; FISH is a protocol developped for the GNU Midnight Commander | ||
| 29 | ;; <https://savannah.gnu.org/projects/mc>. A client connects to a | ||
| 30 | ;; remote host via ssh (or rsh, shall be configurable), and starts | ||
| 31 | ;; there a fish server via the command "start_fish_server". All | ||
| 32 | ;; commands from the client have the form "#FISH_COMMAND\n" (always | ||
| 33 | ;; one line), followed by equivalent shell commands in case there is | ||
| 34 | ;; no fish server running. | ||
| 35 | |||
| 36 | ;; The fish server (or the equivalent shell commands) must return the | ||
| 37 | ;; response, which is finished by a line "### xxx <optional text>\n". | ||
| 38 | ;; "xxx" stands for 3 digits, representing a return code. Return | ||
| 39 | ;; codes "# 000" and "# 001" are reserved for fallback implementation | ||
| 40 | ;; with native shell commands; they are not used inside the server. See | ||
| 41 | ;; <http://cvs.savannah.gnu.org/viewcvs/mc/vfs/README.fish?root=mc&view=markup> | ||
| 42 | ;; for details of original specification. | ||
| 43 | |||
| 44 | ;; The GNU Midnight Commander implements the original fish protocol | ||
| 45 | ;; version 0.0.2. The KDE Konqueror has its own implementation, which | ||
| 46 | ;; can be found at | ||
| 47 | ;; <http://websvn.kde.org/branches/KDE/3.5/kdebase/kioslave/fish>. It | ||
| 48 | ;; implements an extended protocol version 0.0.3. Additionally, it | ||
| 49 | ;; provides a fish server implementation in Perl (which is the only | ||
| 50 | ;; implementation I've heard of). The following command reference is | ||
| 51 | ;; based on that implementation. | ||
| 52 | |||
| 53 | ;; All commands return either "### 2xx\n" (OK) or "### 5xx <optional text>\n" | ||
| 54 | ;; (NOK). Return codes are mentioned only if they are different from this. | ||
| 55 | ;; Spaces in any parameter must be escaped by "\ ". | ||
