more 386 runtime: remove use of _subv in vlrt.c darwin/386/signal.c darwin/386/* linux/386/* (forgotten before) can run empty program on darwin/386 now. R=r DELTA=1140 (1021 added, 114 deleted, 5 changed) OCL=26942 CL=26968

runtime: use new #include "textflag.h" I did this just to clean things up, but it will be important when we drop the pkg directory later. LGTM=bradfitz R=r, bradfitz CC=golang-codereviews https://golang.org/cl/132600043

runtime: change 386 startup convention Now the default startup is that the program begins at _rt0_386_$GOOS, which behaves as if calling main(argc, argv). Main jumps to _rt0_386. This makes the _rt0_386 entry match the expected semantics for the standard C "main" function, which we can now provide for use when linking against a standard C library. 386 analogue of https://golang.org/cl/7525043 R=golang-dev, r CC=golang-dev https://golang.org/cl/7551045

runtime: for c-archive/c-shared, install signal handlers synchronously The previous behaviour of installing the signal handlers in a separate thread meant that Go initialization raced with non-Go initialization if the non-Go initialization also wanted to install signal handlers. Make installing signal handlers synchronous so that the process-wide behavior is predictable. Update #9896.

runtime: convert a few traceback-related functions from proc.c to traceback.go They were in proc.c mainly because there was no portable traceback source file. As part of converting them to Go, move to traceback.go. In order to get access to the PC of _rt0_go, rename to runtime.rt0_go.
