JSONRPC: Increase network performance

Axel Gembe 6661ca7e1b
Reduce memory allocations when generating the merkle root 
When generating the merkle root, the previous code calls `malloc`
once for every transaction, which is not ideal for performance.

The new code allocates a 32 KiB buffer once and reuses it for all
transactions. If a TX is bigger than the current buffer size, the
buffer is reallocated with double the current buffer size.

Speed up hex2bin function 
The existing function uses `strtol`, which is not very fast.

This replaces the function with a custom hex decoder.

Speed up generation of TX buffer in merkle root generation 
The `gbt_work_decode` function builds a long string of all the
transactions (`work->txs`) when generating the merkle root. This
is done inefficiently using `strcat` on the beginning of the
buffer for each TX. `strcat` will take more time the longer the
string is.

To fix this, we keep track of the end of the end of the string and
use `strcpy` to directly write the current TX there.

JSONRPC: Preallocate receive buffer based on Content-Length header 
Decreases the amount of reallocations needed to receive the response.

JSONRPC: Increase network performance by reducing the reallocation count 
The `all_data_cb` callback was called by `libcurl` with small buffers
causing frequent reallocations, which killed network performance on large
block templates.

The new code decouples content length from allocation size. It starts out
by allocating a minimum of 16 KiB and doubles the buffer size every time
the allocation gets too small. The maximum allowed increase after doubling
is capped to 8 MiB.
