    http.c: Unify read operations

    So far, libweb would perform different read operations depending on its
    state:

    - For HTTP headers or request bodies, one byte at a time was read.
    - For multipart/form-data, up to BUFSIZ bytes at a time were read.

    However, this caused a significant extra number of syscalls for no
    reason and would increase code complexity, specially when parsing
    multiform/form-data boundaries.

    Now, http_read always reads up to BUFSIZ bytes at a time and process
    them on a loop. Apart from reducing code complexity, this should
    increase performance due to the (much) lower number of syscalls
    required.
