lib: added key string constants, chainparams and bip32/44 wrappers

[edtubbs]

address: added depth to dogecoin_hd_generate_key for extended keys
chainparams: added isTestnetFromB58Prefix and isMainnetFromB58Prefix wrappers
bip32: added wrappers and depth to dogecoin_hd_generate_key for extended keys
bip39: moved constant to header
bip44: added wrappers and updated to derive_bip44_extended_key
key: added wrappers
dogecoin: added key string and script constants
example: moved constants to header, updated for key string constants, indentation and to derive_bip44_extended_key
tool: added wrappers, assert for dogecoin_pubkey_get_hex call and depth to dogecoin_hd_generate_key for extended keys
tx: added wrapper
vector: added wrappers for serialization/deserialization
test: added wrappers to bip32, key, transaction, tool, and vector tests

one thing i just noticed with regards to the tool test is there are no guards per hardening within hd_derive. i'm wondering if this should return an error prompt if a user passes ' or h? for instance, adding a ' or h:

    size_t extoutsize = 200;
    char* extout=dogecoin_char_vla(extoutsize);
    const char* privkey = "dgpv557t1z21sLCnAz3cJPW5DiVErXdAi7iWpSJwBBaeN87umwje8LuTKREPTYPTNGXGnB3oNd2z6RmFFDU99WKbiRDJKKXfHxf48puZibauJYB";
    debug_print("\nMaster private key:  %s\n", privkey);

    u_assert_int_eq(hd_derive(&dogecoin_chainparams_main, privkey, "m/0h", extout, extoutsize), true);
    // u_assert_str_eq(extout, "dgpv55wVA8mg2HkLPXa4bSyi83hbXrwVWsiTE2Z3kSTUtC6QUyg3ed3FprcvAFKWUSvyRtaPuVwfbcQMQqVXM12yrxQtSCB2iPF4A6RdDp53jjy");
    printNode(false, extout);

yields an overflow here:

this isn't a blocker per this pr but just wanted to note.

ACK, built and tested on x86_64-pc-linux-gnu.

big PR but much of that i know is whitespace/tab deletion, lgtm though.
