same as subtype_adbe_x509_rsa_sha1, with changed last byte

prints in hex format ASN1_OCTET_STRING

minor code fixes

ERR_NO -> ERR_NONE
minor code fixes

Moved sigil_err_string to sigil.h, where all the public funcitons are

check data integrity - hash inside the signature equals computed
 hash over provided range

added openssl library

Read /Cert, /Contents and /ByteRange from signature dictionary. This
still needs to be improved, but looks like it at least partially works.

// It started as branch for adding UTF-8 support, but ended differently

    remove char_t, using UTF-8 narrow strings

now possible to set data as one of the following:
 - FILE *
 - path to the file (const char *)
 - char *, pointing to the pdf content

all data related operations got their custom functions

if the input source is file and its size is under threshold defined
 in config.h, all the content is loaded into memory

removed error module
added module types + constants
other small improvements

added
  - tests
  - fn add_xref_entry
  - fn free_xref_entry
  - fn xref_init
  - fn xref_free
  - fn read_xref_table
  - fn print_xref
  - fn skip_leading_whitespaces
  - fn parse_keyword
removed
  - modes (also sigil_process -> sigil_verify)

for now without tests
