Now, cleared 'elapsed' timer. All time measurement is done in the benchmark() function. Created a timer inside of main() function to show total spent time.
The general square root calculations are not necessary in FreeType.
For vector normalization or length, FreeType uses special functions.
It is, however, required in the legacy CFF specifications.
* src/base/ftcalc.c (FT_SqrtFixed): New function that uses either
Babylonian or bit-wise algorithm, whichever is faster for the given
situation.
* include/freetype/internal/ftcalc.h (FT_SqrtFixed): Declare it.
When matching the keywords, we avoid calculating their lengths by
checking the stored values. This itself is a sufficient pre-check
before diving into `memcmp`. Therefore, we remove explicit check of
the first characters.
* include/freetype/internal/psaux.h (T1_FieldRec): Store length.
* src/cid/cidload.c (cid_parse_dict): Use `memcmp` and stored length.
* src/type1/t1load.c (parse_dict): Ditto.
* src/type42/t42parse.c (t42_parse_dict): Ditto.
* src/cff/cffobjs.c (remove_style): Rewrite using pointers.
(remove_subset_prefix): Unwrap loop and use `memmove`.
* src/truetype/ttobjs.c (tt_skip_pdffont_random_tag): Unwrap loop
and avoid `strlen`.
This also reduces the used heap size by a large factor.

* src/autofit/afcjk.h (AF_CJKAxisRec): Use `AF_BLUE_STRINGSET_MAX_LEN`.
* src/autofit/aflatin.h (AF_LatinAxisRec): Ditto.

The behaviour changed in GNU make 4.3, where `#` (without the backslash)
would be necessary. Using a variable instead the code works with both older
and newer GNU make versions.
Fixes#1252.
FreeType's `refdoc` target currently allows users to override the
default Python path, which is useful for testing and development.
In contrast, `mkdocs` is invoked via the default Python path.
Invoking `mkdocs` via Python's module syntax allows for greater
flexibility, although there is no change for the default use case.
`FT_NEW_ARRAY(p, 0)` sets `p` to `NULL`. `FT_Stream_ReadAt` with a
memory based stream uses `FT_MEM_COPY` which is `memcpy` which specifies
that it is undefined behavior for either the `src` or `dst` to be
`NULL`. Instead of forcing all callers work around calling
`FT_Stream_Read` when `buffer == NULL && count == 0` do the check in
`FT_StreamRead`. This allows any call with `count == 0` to succesfully
read zero bytes without UB.
* src/base/ftstream.c (FT_Stream_ReadAt): skip `FT_MEM_COPY` when
`count == 0`. (FT_Stream_TryRead): ditto
Fixes: #1250
