Fix ht default size test
in the line:
size != 0 ? : (size = DEFAULT_HT_SIZE);
we should notice that the lack of ( ) around "size != 0" leads to the
following behavior: the compiler will try to evaluate
"0 ? : (size = DEFAULT_HT_SIZE)"
and compare it to size, which is not the expected behavior.
Use a standard "if (cond)" test instead. The ? : expression is not
needed here anyway, it just complicates the code.

The channel, ust-app side, was added to the hash table of the session

lttng-sessiond: do not call ustctl_register_done()
When lttng-ust support is not enabled, compilation might fail with:
lttng-tools.git/lttng-sessiond/main.c:1167: undefined reference to
`ustctl_register_done'
Actually when HAVE_LIBLTTNG_UST_CTL is not defined, the function call is
normally optimized out by the compiler because ust_app_register() is a
static inline alway returning a negative value, leaving the call within
unreachable code.
Depending on the compiler version and optimization flags, this may
however not always happen, leading to the above error.
Therefore replace ustctl_register_done() with ustapp_register_done(),
which calls the original function when lttng-ust is enabled, and returns

Use the consumerd_bin variables for kernel consumers too
Right now the sessiond will only look in its own directory for
the consumerd when starting a kernel trace. This patch makes it
check for consumerd32_bin and consumerd64_bin too.

Rename consumerd32/64_path options to _bin
The _path suffix was confusing as to whether it would include the
filename at the end or not. In fact it should (to allow greater
flexibility in moving/renaming the consumerd executable).
Rename all configure options, env vars and substition variables to
consumerd32/64_bin instead, and expect the user to pass a complete
basename + filename to those.
