util/slab: re-design to allow migration between pools (v3)

This is basically a re-write of the slab allocator into a design where
multiple child pools are linked to a parent pool. The intention is that
every (GL, pipe) context has its own child pool, while the corresponding
parent pool is held by the winsys or screen, or possibly the GL share group.

The fast path is still used when objects are freed by the same child pool
that allocated them. However, it is now also possible to free an object in a
different pool, as long as they belong to the same parent. Objects also
survive the destruction of the (child) pool from which they were allocated.

The slow path will return freed objects to the child pool from which they
were originally allocated. If that child pool was destroyed, the corresponding
page is considered an orphan and will be freed once all objects in it have
been freed.

This allocation pattern is required for pipe_transfers that correspond to
(GL) buffer object mappings when the mapping is created in one context
which is later destroyed while other contexts of the same share group live
on -- see the bug report referenced below.

Note that individual drivers do need to migrate to the new interface in
order to benefit and fix the bug.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=97894

util: use GCC atomic intrinsics with explicit memory model

This is motivated by the fact that p_atomic_read and p_atomic_set may
somewhat surprisingly not do the right thing in the old version: while
stores and loads are de facto atomic at least on x86, the compiler may
apply re-ordering and speculation quite liberally. Basically, the old
version uses the "relaxed" memory ordering.

The new ordering always uses acquire/release ordering. This is the
strongest possible memory ordering that doesn't require additional
fence instructions on x86. (And the only stronger ordering is
"sequentially consistent", which is usually more than you need anyway.)

I would feel more comfortable if p_atomic_set/read in the old
implementation were at least using volatile loads and stores, but I
don't see a way to get there without typeof (which we cannot use here
since the code is compiled with -std=c99).

Eventually, we should really just move to something that is based on
the atomics in C11 / C++11.

mesa: Raise INVALID_ENUM in FramebufferTexture*D for unknown textargets.

ES3-CTS.functional.negative_api.buffer.framebuffer_texture2d expects
glFramebufferTexture[123]D to raise GL_INVALID_ENUM when
supplied a completely bogus textarget parameter (i.e. 0xffffffff).

This is at odds with the spec.  GLES 3.1 says:

   "An INVALID_OPERATION error is generated if texture is not zero and
    textarget is not one of TEXTURE_2D, TEXTURE_2D_MULTISAMPLE, or one
    of the cube map face targets from table 8.21."

(and GLES 3.0 and GL 4.5 both have similar text).  However, GL has a
general guideline that says:

   "If a command that requires an enumerated value is passed a symbolic
    constant that is not one of those specified as allowable for that
    command, an INVALID_ENUM error is generated."

Apparently other vendors reconcile these two rules as follows: GL should
raise INVALID_OPERATION for actual texture target enumeration values
which are not allowed for this particular glFramebufferTexture*D call.
Any value that is not a texture target should result in GL_INVALID_ENUM.

For example, glFramebufferTexture2D with GL_TEXTURE_1D would result in
INVALID_OPERATION because it is a real texture target, but not allowed
for the 2D version of the function.  But calling it with GL_FRONT would
result in INVALID_ENUM, as that isn't even a texture target.

aubinator: Use less -RS instead of -r for the implicit pager.

From the less man page:

   "Warning: when the -r option is used, less cannot keep track of the
    actual appearance  of  the screen (since this depends  on  how the
    screen responds to each type of control character).  Thus, various
    display problems may result, such as long lines being split in the
    wrong place."

Lines which are too long to fit in the terminal would be word wrapped,
but unfortunately less would get confused about which line it was on,
and text would be drawn on top of other text.  The most noticable case
was shader assembly, which is frequently too wide for an 80 character
terminal, and thus would be drawn on top of the following state packets,
making them completely unreadable.

Using -R instead of -r fixes this problem by only allowing color escape
sequences.  (Notably, Git's implicit pager invocation uses -R.)
Unfortunately, it means our "clear to the end of the line" hack for
extending the blue bar headers won't work anymore.

Word wrapping usually isn't terribly readable, anyway, so we also add
the -S option (chop long lines) to restrict it to the terminal width.
(You can hit the left and right arrow keys to scroll sideways.)

Then, for a new blue bar hack, we can use a printf specifier to pad
the command packet names to be 80 characters long (arbitrarily), which
extends them "far enough" to look good, and doesn't require us to use
ioctls to determine the terminal width.

However, it looks like Gen7 doesn't need this.  The push constant atom
emits 3DSTATE_CONSTANT_VS directly, and the gen7_vs_state atom that
emits 3DSTATE_VS doesn't have a dependency on ctx->Transform.

glsl: Kill __intrinsic_atomic_sub

Just generate an __intrinsic_atomic_add with a negated parameter.

Some background on the non-obvious reasons for the the big change to
builtin_builder::call()... this is cribbed from some discussion with
Ilia on mesa-dev.

Why change builtin_builder::call() to allow taking dereferences and
create them here rather than just feeding in the ir_variables directly?
The problem is the neg_data ir_variable node would have to be in two
lists at the same time: the instruction stream and parameters.  The
ir_variable node is automatically added to the instruction stream by the
call to make_temp.  Restructuring the code so that the ir_variables
could be in parameters then move them to the instruction stream would
have been pretty terrible.

ir_call in the instruction stream has an exec_list that contains
ir_dereference_variable nodes.

The builtin_builder::call method previously took an exec_list of
ir_variables and created a list of ir_dereference_variable.  All of the
original users of that method wanted to make a function call using
exactly the set of parameters passed to the built-in function (i.e.,
call __intrinsic_atomic_add using the parameters to atomicAdd).  For
these users, the list of ir_variables already existed:  the list of
parameters in the built-in function signature.

This new caller doesn't do that.  It wants to call a function with a
parameter from the function and a value calculated in the function.  So,
I changed builtin_builder::call to take a list that could either be a
list of ir_variable or a list of ir_dereference_variable.  In the former
case it behaves just as it previously did.  In the latter case, it uses
(and removes from the input list) the ir_dereference_variable nodes
instead of creating new ones.
