a54570352a [maybe] bytevm: open-code lexical environment allocation 
To avoid dependency on vector.o we opencode allocating the vector.

Note that we can't use ecl_make_stack, because mallocated memory must be
reegistered as a root.

[todo] move finalizers to memory and fix t_bclosure
[note] ecl_stack_pshu never resizes the stack (realloc vs manual resize)

357ef042ed [maybe] boot: introduce a table with early symbols ecl_symbols 
This table contains symbols that are essential to the core runtime: ECL_T,
ECL_UNBOUND, ECL_SIGNAL_HANDLERS, ECL_RESTART_CLUSTERs, ECL_INTERRUPTS_ENABLED,
ECL_ALLOW_OTHER_KEYS and ECL_UNBOUND.

The table is initialized with constexpr, so it is possible to use its elements
in static elements. We also add ecl_def_function to ecl-inl to allow
appropriating C functions into Lisp world at top level.

12f1458a32 memory: ensure disabled interrupts in top-level operators 
ecl_alloc_object, ecl_free_object
ecl_alloc, ecl_alloc_manual, ecl_alloc_atomic, ecl_dealloc

Moreover move all top-level ops to memory.d so they are not reliant on mem_gc.
The stubbed allocator uses manual memory managament for all ops.

de73c24bd4 memory: move resource pools from reader.d to memory.d 
si_get_buffer_string is used in a few places, and gneerally it is more
appropriate to put resources in memory.

7d7352cf6b memory: reify the type_info database

information is later reused by the garbage collector.

ee4dcb7a62 memory: move ecl_alloc_adjustable_*_string to memory.d

4fc8bb7c45 memory: move ecl_cons to memory.d 
ecl_cons requires a separate allocator because it may be a small cons.

bc8385486b stacks: move early stacks to a separate file

8776a249d6 modules: [B/n] allow for building ecl without bdwgc and with nogc 
In that case we use a dummy object nogc.o that contains stubs for GC-related
functions. It also defines a substitute module.

d875e235eb modules: release all resources on ecl_halt

we do perform a proper shutdown.

30bccdefcf garbage: register and unregister GC threads manually from a module 
This decouples thread primitives from the garbage collector and allows us to
build nucl once more.

1eb9822065 process: abstract away create thread, exit thread and sigmask 
Previously we've opencoded calls to these functions, although they may be nicely
abstracted with static inline functions. This change improves code readibility
and portability.

79c56803b5 modules: [1/n] introduce ecl_module_gc 
We also remove conditionalization for garbage collector inclusion in autotools.
When we propose an alternative gc, then we may decide to put them back, or to
add necessary ifdef statements directly in files.

Moreover untangle c-stack from the gc code and assign the stack base with a
rough guess only when it is not initialized yet (GC will always fill it).

Finally remove a kludge from ecl_adopt_cpu and disable colleciton until the cpu
is fully initialized.

e463ff4f85 signals: define *SIGNAL-HANDLERS* in cold_boot 
I've also renamed *HANDLER-CLUSTERS* to a more appropriate *SIGNAL-HANDLERS*.
Currently this symbol is imported to the SYSTEM package, although this may be
revised in the future to cater to multiple global environments. Alternatively
the SYSTEM package may be common to all runtimes.

06483e14d8 signals: rewrite signal handling to use functions and not lists 
Instead of storing lists in *HANDLER-CLUSTERS*, we define functions that are
called unconditionally on the handler. HANDLER-BIND defines that function to be
a typecase that is dispatched based on the conditiont type, as specified by CL.

This change will aid further refactor.

fb703882b8 hash: rename cl__make_hash_table to ecl_make_hash_table 
The latter name follows the codebase convention that functions that do not work
in the environment have a prefix ecl_. The old name is defined in legacy.h.
