/*
 * str_stk.h  - maintains a stack of the components of a bit string
 * or octet string so they can be copied into a single chunk
 *
 *
 *  CONSTRUCTED BIT AND OCTET STRINGS SUCK. They should be
 *  specified in the application's ASN.1 spec as SEQUENCE OF OCTET STRING
 *
 * this stack stuff is for decoding constructed bit/octet strings
 * so the user gets a single contiguous bit/octet str instead of
 * irritating little pieces.  This does not cost a lot more than
 * a linked octet/bit string type since we're copying from the
 * buffer anyway, not referencing it directly (even in simple case).
 * It will cost more if the string stk overflows and
 * needs to be enlarged via realloc - set the values of
 * initialStkSizeG, and stkGrowSize carefully for your application.
 * Once the StkSize grows, it doesn't shrink back ever.
 *
 * Only three routine use/deal with this stack garbage
 *  BDecConsAsnOcts
 *  BDecConsAsnBits
 *  SetupConsBitsOctsStringStk
