Remove the pre_allocate argument from hb_buffer_create()
...
For two reasons:
1. User can always call hb_buffer_pre_allocate() themselves, and
2. Now we do a pre_alloc in add_utfX anyway, so the total number of
reallocs is limited to a small number (~3) anyway. This just makes the
API cleaner.

Pre-allocate buffers when adding string
...
We do a conservative estimate of the number of characters, but still,
this limits the number of buffer reallocs to a small constant.

[API] Changes to main shape API
...
hb_shape() now accepts a shaper_options and a shaper_list argument.
Both can be set to NULL to emulate previous API. And in most situations
they are expected to be set to NULL.
hb_shape() also returns a boolean for now. If shaper_list is NULL, the
return value can be ignored.
shaper_options is ignored for now, but otherwise it should be a
NULL-terminated list of strings.
shaper_list is a NULL-terminated list of strings. Currently recognized
strings are "ot" for native OpenType Layout implementation, "uniscribe"
for the Uniscribe backend, and "fallback" for the non-complex backend
(that will be implemented shortly). The fallback backend never fails.
The env var HB_SHAPER_LIST is also parsed and honored. It's a
colon-separated list of shaper names. The fallback shaper is invoked if
none of the env-listed shapers succeed.
New API hb_buffer_guess_properties() added.

[buffer] Remove wrong optimization
...
While the cluster fields of the glyph string are usually sorted, they
wouldn't be in special cases (for example for non-native direction).
Blindly using bsearch is plain wrong. If we want to reintroduce this
optimization we have to make sure we know the buffer clusters are
monotonic and in which direction. Not sure it's worth it though.
