A new function `STRBUF_INIT_CONST(const_str)` was added to allow for a
quick initialization of strbuf.
Details:
Using `STRBUF_INIT_CONST(str)` creates a new struct of type `strbuf` and
initializes its `buf`, `len` and `alloc` as `str`, `strlen(str)` and
`0`, respectively.
Use Case:
This is meant to be used to initialize strbufs with constant values and
thus, only allocating memory when needed.
Usage Example:
```
strbuf env_var = STRBUF_INIT_CONST("dev");
```
This was added according to the issue opened at [https://github.com/gitgitgadget/git/issues/398]
