They were broken due to previous commit. Fixes are trivial.

First, that test was broken from the previous commit because the
channel_queue_cell() has been removed. This now tests the
channel_process_cell() directly.
Second, it wasn't testing much except if the channel subsystem actually went
through the cell handler. This commit adds more checks on the state of a
channel going from open, receiving a cell and closing.
Third, this and the id_map unit test are working, not the others so they've
been marked as not working and future commit will improve and fix those.

The channel_write_cell() and channel_write_var_cell() can't be possibly called
nor are used by tor. We only write on the connection outbuf packed cell coming
from the scheduler that takes them from the circuit queue.
This makes channel_write_packed_cell() the only usable function. It is
simplify and now returns a code value. The reason for this is that in the next
commit(s), we'll re-queue the cell onto the circuit queue if the write fails.
Finally, channel unit tests are being removed with this commit because they do
not match the new semantic. They will be re-written in future commits.

The channel subsystem was doing a whole lot to track and try to predict the
channel queue size but they are gone due to previous commit.

For the rationale, see ticket #23709.
This is a pretty massive commit. Those queues were everywhere in channel.c and
it turns out that it was used by lots of dead code.
The channel subsystem *never* handles variable size cell (var_cell_t) or
unpacked cells (cell_t). The variable ones are only handled in channeltls and
outbound cells are always packed from the circuit queue so this commit removes
code related to variable and unpacked cells.
However, inbound cells are unpacked (cell_t), that is untouched and is handled
via channel_process_cell() function.
In order to make the commit compile, test have been modified but not passing
at this commit. Also, many tests have been removed but better improved ones
get added in future commits.
This commit also adds a XXX: which indicates that the handling process of
outbound cells isn't fully working. This as well is fixed in a future commit.
Finally, at this commit, more dead code remains, it will be cleanup in future
commits.
Fixes #23709

The `test-operator-cleanup` patch, and related coccinelle patches,
don't do any checks for line length. This patch fixes the line
length issues caused by the previous commits.

This patch fixes the operator usage in src/test/*.c to use the symbolic
operators instead of the normal C comparison operators.
This patch was generated using:
./scripts/coccinelle/test-operator-cleanup src/test/*.[ch]

This reduces the size of the largest SCC in the callgraph by 30
functions, from 58 to 28.

This was breaking the build on debian precise, since it thought that
using a 'const int' to dimension an array made that array
variable-size, and made us not get protection.
Bug not in any released version of Tor.
I will insist that this one wasn't my fault.

This is a big-ish patch, but it's very straightforward. Under this
clang warning, we're not actually allowed to have a global variable
without a previous extern declaration for it. The cases where we
violated this rule fall into three roughly equal groups:
* Stuff that should have been static.
* Stuff that was global but where the extern was local to some
other C file.
* Stuff that was only global when built for the unit tests, that
needed a conditional extern in the headers.
The first two were IMO genuine problems; the last is a wart of how
we build tests.

This warning triggers on silently promoting a float to a double. In
our code, it's just a sign that somebody used a float by mistake,
since we always prefer double.

channel_write_*_cell() can delete its argument, so coverity doesn't
like us doing pointer comparison against that argument later.
Silly.
