* tool/compile_prelude.rb (translate): remove comments which are
not used in compiled sources.

th->base_block is information for (a) parsing, (b) compiling
and (c) setting up the frame to execute the program passed by
`eval' method. For example, (1) parser need to know up-level
variables to detect it is variable or method without paren.
Befor (a), (b) and (c), VM set th->base_block by passed bindng
(or previous frame information). After execute (a), (b) and (c),
VM should clear th->base_block. However, if (a), (b) or (c)
raises an exception, then th->base_block is not cleared.
Problem is that the uncleared value th->balo_block is used for
irrelevant iseq compilation. It causes SEGV or critical error.
I tried to solve this problem: to clear them before exception,
but finally I found out that it is difficult to do it (Ruby
program can be run in many places).
Because of this background, I set th->base_block before
compiling iseq and restore it after compiling.
Basically, th->base_block is dirty hack (similar to global
variable) and this patch is also dirty.
* bootstraptest/test_eval.rb: add a test for above.
* internal.h: remove unused decl.
* iseq.c (rb_iseq_compile_with_option): add base_block parameter.
set th->base_block before compation and restore it after
compilation.
* ruby.c (require_libraries): pass 0 as base_block instead of
setting th->base_block
* tool/compile_prelude.rb (prelude_eval): apply above changes.
* vm.c, vm_eval.c: ditto.
* vm_core.h: add comments.

so that copy & paste for lib/rubygems/default.rb is not necessary.
* gem_prelude.rb: removes copied codes from lib/rubygems/defaults.rb.
uses require instead.
* common.mk (prelude.c): adds dependency for lib/rubygems/defaults.rb.

* enc/Makefile.in: became a serb template.
* enc/make_encmake.rb: creates enc.mk from enc/Makefile.in using serb.
* lib/mkmf.rb (relative_from): moved from ext/extmk.rb.
* lib/mkmf.rb ($extmk): true if under to top source directory, not
only ext.
* lib/mkmf.rb (depend_rules): extracted from create_makefile.
* tool/serb.rb (serb): splitted from tool/compile_prelude.rb.

* common.mk: generate ext_prelude.c by prelude.rb and gem_prelude.rb.
ruby (not miniruby) is linked with ext_prelude.o instead of prelude.o.
* inits.c (rb_call_inits): don't call Init_prelude.
* ruby.c: support --disable-gems option.
(ruby_init_gems): new function to define Gem::Enable and
invoke Init_prelude.
(process_options): call ruby_init_gems just after
ruby_init_loadpath.
* tool/compile_prelude.rb: support multiple files.
